摘要：
The biosorption characteristics of U(VI) from aqueous solution onto a nonliving aquatic macrophyte, Hydrilla verticillata (dry powder), were investigated under various experimental conditions by using batch methods. Results showed that the adsorption reached equilibrium within 60 min and the experimental data were well fitted by the pseudo-first-order kinetic model. U(VI) adsorption was strongly pH dependent, and the optimum pH for U(VI) removal was 5.5. Isotherm adsorption data displayed good correlation with the Langmuir model, with a maximum monolayer adsorption capacity of 171.52 mg/g. Thermodynamic studies suggested that U(VI) adsorption onto H. verticillata was an exothermic and spontaneous process in nature. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy indicated that the amino and hydroxyl groups on the algal surface played an important role in U(VI) adsorption. The mechanisms responsible for U(VI) adsorption could involve electrostatic attraction and ion exchange. In conclusion, H. verticillata biomass showed good potential as an adsorption material for the removal of uranium contaminants in aqueous solution.

摘要：
Ceratophyllum demersum was used to remove U(VI) from aqueous solution. Effects of various adsorption parameters such as pH, shaking time, initial U(VI) concentration, and temperature were investigated. The optimum pH for U(VI) removal was 5.0. Pseudo-first-order kinetic model and Langmuir isotherm model could best describe the adsorption process. The maximum monolayer adsorption capacity was 140.45 mg/g. Thermodynamic calculations suggested that the U(VI) adsorption process was spontaneous and exothermic. The amino, hydroxyl, and carbonyl groups on the algal surface could contribute to U(VI) adsorption. The present study suggested that C. demersum biomass could be an efficient biosorbent to remove U(VI) contaminants.

摘要：
In recent years, some two-dimensional nanomaterials, such as graphene and molybdenum disulfide, cause extensive interests from scientists due to their excellent performances. In this paper, MoS<inf>2</inf>was synthesized by a simple hydrothermal method without any assisted reagents, the MoS<inf>2</inf>nanosheets display relatively high photocatalytic activity of p-nitrophenol degradation under visible light illumination (λ>420 nm). Some experimental reaction conditions were optimized, the highest degradation efficiency of 55.0% is obtained within 120 min at initial 10.0 mg L<sup>−1</sup>p-nitrophenol when the MoS<inf>2</inf>is prepared at 200 °C for 20 h with the mole ratio of S/Mo = 1/1. A probable mechanism of photo-degradation was discussed. To our knowledge, there are no other reports on MoS<inf>2</inf>photocatalytic degradation of phenolic compounds including p-nitrophenol so far. The present report is expected to contribute toward the disposal of highly toxic pollutant under visible light.

摘要：
Some two-dimensional nanomaterials, such as graphene and molybdenum disulfide, are presently being intensively investigated due to their excellent and unique performances. In the field of photocatalysis, MoS<inf>2</inf>is considered as a promising alternative to noble metal Pt for the hydrogen evolution reaction (HER). However, its poor electrical conductivity restricts its catalytic activity in the HER. In this work, MoS<inf>2</inf>was modified with graphene (G) by a simple hydrothermal method. The prepared G/MoS<inf>2</inf>composite was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results show that graphene modification does not influence the crystal phase of MoS<inf>2</inf>, but makes the latter more dispersed. The HER performance of G/MoS<inf>2</inf>was evaluated using eosin Y (EY) as a photosensitizer, and triethanolamine (TEOA) as a sacrificial electron donor under visible-light irradiation (λ>420 nm, 250 W high pressure Hg lamp as light source). The EY sensitized G/MoS<inf>2</inf>composite displays enhanced hydrogen evolution in terms of not only activity but also stability. The average HER activity (9.1 μmol h<sup>-1</sup>) is three times that of EY sensitized pure MoS<inf>2</inf>over 10 h. It is believed that the incorporation of graphene enhances the charge transfer ability and retards the self-degradation path of EY<sup>-</sup>, ultimately improving the HER. ©2017 The Royal Society of Chemistry.

摘要：
有机磷杂环化合物9, 10-二氢-9-氧杂-10-膦杂菲-10-氧化物(DOPO)因性能优异而作为无卤阻燃剂得到广泛应用。为了提升和改进DOPO的合成,不少文献对合成中的4个反应,即酯化反应、酰基化反应、水解反应和关环反应进行了大量研究,但是由于缺少合适的分析方法和仪器,对酯化反应和酰基化反应仍没有得出明确的结论。本文则采用了核磁共振磷谱以及测量反应产物HCl吸收碱液的温度变化两种方法,精确地得到了酯化反应和酰基化反应的优化条件。首先采用核磁共振磷谱,讨论了酯化反应温度、原料配比和加料方式对酯化反应产物组成的影响,得出了邻苯基苯氧基二氯化磷(CC)含量高的工艺条件:反应温度80 ℃, PCl_3过量25% ~ 50%,采用邻苯基苯酚(OPP)加入PCl_3的反滴法; 并得出酯化反应产物的组成直接决定了6-氯-(6氢) -二苯并-(c,e) -氧磷杂己环(CDOP)在酰基化反应产物中的含量。另通过测量HCl吸收碱液的温度变化,间接表征酰基化反应的反应速度,由此得出合适的酰基化反应温度和催化剂用量。结果为: 当催化剂固定为0. 2 g时,酰基化反应在150 ℃几乎不反应,随温度升高,反应变快, 180 ℃下4 h完全, 190 ℃下1. 5 h即可完成; 温度180 ℃下,1 ~ 1. 5 g /1 mol OPP的催化剂较为合适,酰基化反应在3 ~ 4 h结束。

摘要：
BACKGROUND: Photocatalytic degradation of organic compounds, including nitrophenol, is one of the most popular approaches to pollution control and disposal. Graphene-based nanocomposites have attracted considerable attention in photocatalytic research owing to their excellent electrical, thermal and mechanical properties. In this work, TiO<inf>2</inf>material was modified with graphene by a hydrothermal method, the photocatalytic performance of the prepared catalyst was evaluated by degradation of 4-nitrophenol, which is a highly toxic, stable and carcinogenic organic pollutant. RESULTS: The characterization results showed that the low amount of graphene disperses well over TiO<inf>2</inf>and it does not influence the crystal phase, but makes the specific surface area of graphene/TiO<inf>2</inf>greater than that of TiO<inf>2</inf>. Compared with TiO<inf>2</inf>, graphene/TiO<inf>2</inf>exhibits enhanced photocatalytic activity for the degradation of 4-nitrophenol under simulated solar irradiation. CONCLUSION: The enhanced activity of photo-degradation could be attributed to the involved graphene being beneficial to charge transportation and separation of photogenerated charge carriers, and providing more surface active sites for degradation reaction of the target pollutant. The present result highlights the important application of graphene as a novel carbon material in treating highly toxic pollutant through photocatalysis technology. ©2017 Society of Chemical Industry. ©2017 Society of Chemical Industry

摘要：
6-氯-(6氢)-二苯并-(c,e)-氧磷杂己环(CDOP)是阻燃剂9,10-二氢-9氧杂-10-膦杂菲-10-氧化物(DOPO)制备中最重要的中间体,而常规的CDOP合成过程中,原料邻苯基苯酚(OPP)和三氯化磷(PCl3)之间的酯化反应除了生成单酯(邻苯基苯氧基二氯化磷,CC),还有少量二酯(氯代亚磷酸二邻苯基苯酯,OPPC)和三酯(亚磷酸三邻苯基苯酯,TOPP),导致后续酰基化反应产物CDOP中含有杂质6-苯氧基-(6氢)-二苯并-(c,e)-氧磷杂己环(PDOP)和TOPP.为了除去杂质,本文提出了一种简便的改进工艺,即在酰基化反应过程中额外滴加PCl3,利用酯交换反应除去PDOP和TOPP,直接得到高纯度的CDOP.

摘要：
A visible-light-driven hydrogen evolution system was constructed in one step with xanthene dye as photosensitizer, triethanolamine (TEOA) as electron donor, Pt as cocatalyst, and Keggin-type silicon-tungsten polyoxometalate (POM) as electron relay. The average rate of hydrogen evolution from the eosin Y-POM-TEOA-PtCl<inf>6</inf><sup>2</sup>- systems is 51.8μmol h<sup>-1</sup>, and the apparent quantum yield is 8.9% during 20 h irradiation (λ>420nm;, a high-pressure Hg lamp was used as the light source). Ultraviolet-visible absorption spectra and fluorescence spectra were used to study the mechanism of charge transfer. A radical anion Dye<sup>-</sup>, which generates from quenching of the triplet-excited state<sup>3</sup>Dye∗by sacrificial electron donor, was considered the main species for transmitting electrons to POM and then to Pt. SiW<inf>9</inf>O<inf>34</inf><sup>10-</sup>, derived from SiW<inf>12</inf>O<inf>40</inf><sup>4-</sup>, is the main form of POM in our reaction system, which can mediate the electron transfer from Dye- to Pt, so an enhanced hydrogen evolution was realized. The present study highlights POM as electron relay in the photocatalytic hydrogen evolution process, which is expected to contribute to the development of functional and efficient artificial photosynthetic systems. ©2016 Society of Photo-Optical Instrumentation Engineers (SPIE).

摘要：
In this work, a noble-metal-free homogeneous system was constructed in one step with Keggin-type polyoxometalate (POM) SiW12O404- as a catalyst, Eosin Y as a photosensitizer, and triethanolamine (TEOA) as a sacrificial electron donor for water splitting to produce hydrogen under visible-light irradiation. A two-electron reduced heteropoly blue SiW12O406- is produced by photosensitization under visible-light irradiation. The effect of various component concentrations and POMs with different central atoms (PW12O403-, GeW12O404-, etc.) on hydrogen production was discussed. This simple system made of earth-abundant elements is expected to contribute toward the development of functional and efficient artificial photosynthetic system. © 2016 Elsevier B.V.

摘要：
Batch experiments were conducted to investigate the biosorption of U(VI) from aqueous solutions onto the nonliving biomass of an aquatic macrophyte Eichhornia crassipes. The results showed that the adsorption of U(VI) onto E. crassipes was highly pH-dependent and the best pH for U(VI) removal was 5.5. U(VI) adsorption proceeded rapidly with an equilibrium time of 30 min and conformed to pseudo-second-order kinetics. The Langmuir isotherm model was determined to best describe U(VI) biosorption with a maximum monolayer adsorption capacity of 142.85 mg/g. Thermodynamic calculation results indicated that the U(VI) biosorption process was spontaneous and endothermic. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy analysis implied that the functional groups (amino, hydroxyl, and carboxyl) may be responsible for the U(VI) adsorption process, in which the coordination and ion exchange mechanisms could be involved. We conclude that E. crassipes biomass is a promising biosorbent for the removal of uranium pollutants.

摘要：
理想完全互溶双液系是两个组分都严格遵守Raoult 定律的体系，从数学角度看，其平面相图有着确定的函数关系。本文以Clausius-Clapeyron 方程为基础，推导了该类理想体系的p-x、T-x 及p-T相图的函数解析式。
