摘要:
Mercury ions (Hg(2+)), as one of heavy transition metals (HTM), is a highly toxic metal that is hazardous to human health. Here an aggregation-induced emission (AIE) fluorescent probe is designed for the highly sensitive and selective detection of Hg(2+). The probe is engineered with a tetraphenylethene (TPE) derivative as the fluorophore and thiopropionic acid as the site of recognition for Hg(2+). Due to the different solubilities of the probe AIE-COOH and its corresponding product after reaction with Hg(2+). The probe demonstrates a maximum detection limit of 22nM and a fast response time of∼100s. Simultaneously, AIE-COOH exhibits outstanding detectivity and hypersensitivity for the detection of Hg(2+) in aqueous solutions. These characteristics demonstrate that AIE-COOH hold a great potential in environmental, food and biological systems. Moreover, we have also successfully applied it to Hg(2+) fluorescence imaging in in living cells.

摘要:
In this work, a novel xonotlite nanocomposite was synthesised with abandoned eggshell by hydrothermal method, and organic-modified with toluene diisocyanate (TDI) for the removal of Pb(II) and Cd(II) from wastewater. The xonotlite and organic-modified xonotlite were characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunner-Emmet-Teller (BET) and Fourier transform infrared spectroscopy (FTIR) methods. The effect of solution pH, contact time, adsorbent dose, and initial concentrations were also investigated. The organic-modified xonotlite was found to have a high loading capacity of 467.7 mg g−1 for Pb(II) and 147.6 mg g−1 for Cd(II). The adsorption of Pb (II) and Cd (II) was well fitted by Freundlich model and pseudo-second order model. In the effect of the competing ion, the ions like Na(I) and K(I), had little effect on the Pb(II) and Cd(II) removal efficiency. Furthermore, the organic-modified xonotlite can be reused and shown good recyclability. It was concluded that the organic-modified xonotlite is simple, fast and effective adsorbent for the removal of Pb(II) and Cd(II) in treating wastewater with outstanding adsorption capacity. © 2020 Informa UK Limited, trading as Taylor & Francis Group.

摘要:
The xonotlite was synthesized from eggshell waste and modified with toluene diisocyanate (TDI). The xonotlite and amidoxime-modified xonotlite were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). FTIR revealed that the amidoxime group was successfully grafted onto the xonotlite. Factors affecting adsorption such as solution pH, adsorbent dose, contact time, and initial concentrations were set up to improve the adsorption performance. The adsorption of Cu (II) on all the adsorbents was well-described by the Freundlich model and pseudo-second-order model. The amidoxime-modified xonotlite showed rapid removal efficiency and reached equilibrium in 45 min at the pH of 5. The maximum adsorption capacities for Cu (II) (713.2 mg/g) on the modified xonotlite were 35.8% higher than that on the unmodified xonotlite. The existence of competing ions like K(I) and Na(I) had little effect on the Cu(II) removal efficiency. Therefore, the modified xonotlite could be used as a feasible adsorbent for the removal of Cu (II) in treating wastewater.

摘要:
Sodium, silicate and carbonate ions co-substituted hydroxyapatite adsorbent (Na-SiCHAP) was prepared by sonochemistry coprecipitation. The effect of a variety of parameters on the adsorption of Pb2+ and Cd2+ by Na-SiCHAP were performed. The adsorption process of heavy metal ions was found to follow the pseudo-second-order kinetic equation and Langmuir adsorption model. The maximum absorption capacity (Qm) of Na-SiCHAP for Pb2+ and Cd2+ ions in 303 K were 698.68 and 129.60 mg g−1 according to the Langmuir adsorption model, respectively. The thermodynamic parameters (ΔG0 <0, ΔS0 >0, ΔH0 >22kJ·mol-1) indicated that the absorption of Pb2+ and Cd2+ on the Na-SiCHAP was spontaneous and endothermic, and the Na-SiCHAP adsorbed mainly via chemical adsorption. Ion exchange of Pb2+ and Cd2+ for Ca2+ and Na+ was one of the principal mechanisms, followed by precipitation and electrostatic interactions. Furthermore, the well stability properties of the Na-SiCHAP adsorbent were confirmed by recycling assays. These data indicate that Na-SiCHAP may be a good adsorbent for the rapid removal of heavy metal ions from aqueous solutions. © 2019 Elsevier Inc.

silicon-substituted carbonate hydroxyapatite;Zn2+;adsorption;removal efficiency
摘要:
A kind of low-cost silicon-substituted carbonate hydroxyapatite (Si-CHAP) powder was successfully fabricated by using eggshell powder, H3PO4, Ca(OH)2, Na2SiO3, and Na2CO3 under sonochemistry coprecipitation condition. Si-CHAP could serve as an ideal adsorbent to remove zinc ion (Zn2+) from aqueous solution. Under the optimized conditions, the removal efficiency of Zn2+ in solution by Si-CHAP could reach to 96.2%. The adsorption mechanism was investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. Notably, the adsorption process followed the Langmuir isotherm and pseudo-second-order model, and the saturation adsorption capacities were calculated to be 102.0, 103.1, and 105.3mgg−1 at 293, 303, and 313K, respectively. Thermodynamic studies indicated that the adsorption of Zn2+ by Si-CHAP is endothermic. Mechanism studies revealed that the dominate mechanism was chemical adsorption. These results showed that Si-CHAP is an effective adsorbent for the removal of Zn2+ from aqueous solution, and thus providing a good method to treat Zn2+ in the waste water. © 2018 American Institute of Chemical Engineers Environ Prog, 37: 1901–1907, 2018. © 2018 American Institute of Chemical Engineers

摘要:
Si-substituted carbonate hydroxyapatite (Si-CHAP) was obtained by embedding silicate and carbonate into hydroxyapatite prepared from egg-shell via sonochemistry coprecipitation. Batch experiments were performed to investigate the effect of contact time, solution pH and temperature on the adsorption of Cu2+ by Si-CHAP. Our results showed that the maximal adsorption capacity, Qm of Cu2+ reached to 246.80 mg g–1 at pH 5.7, and at 90 min contact time under 313 K. Adsorption kinetics followed pseudo-second order. The equilibrium process fit the Langmuir isotherm model and the maximum adsorption capacity of Si-CHAP for Cu2+ was found to be 273.51 mg g–1. The thermodynamic studies showed that the adsorption of Si-CHAP on Cu2+ was a spontaneously endothermic process. Si-CHAP was characterized by using FTIR, XRD and SEM-EDS. The mechanism of Cu2+ adsorption by Si-CHAP may include ion exchange, precipitation and electrostatic interactions. Furthermore, the well stability properties of the Si-CHAP adsorbent were confirmed through desorption assays. These results showed that Si-CHAP has the potential to become a cheap and efficient adsorbent to remove Cu2+ from aqueous solutions. © 2018 Desalination Publications. All rights reserved.

摘要:
为了解湘江衡阳段水质的污染现状,分别于2014年的枯水期(1—2月及12月)、平水期(3—4月及10—11月)、丰水期(5—9月),选择湘江衡阳段10个具有代表性的监测断面(包括憩山、松柏、春陵水入口、新塘铺、黄茶岭、蒸水入口、耒水入口、枣子坪、站门前和熬洲),采集并测定水样中Cu、Zn、As、Hg、Cd、Cr(Ⅵ)、Pb的浓度。分别采用单项参数评价法、综合污染指数法、内梅罗污染指数法进行评价。结果表明,湘江衡阳段水体7种重金属的浓度均达到GB 3838—2002《地表水环境质量标准》中的Ⅲ类水水质标准。湘江干流和支流各采样点的综合污染指数均小于0.8,且不同时间水质依次为丰水期〉平水期〉枯水期。仅枯水期松柏水质的内梅罗综合污染指数最高,为0.671,污染等级为Ⅱ级;其余断面水质的内梅罗指数均小于0.59。表明湘江衡阳段总体水质较好,未受到重金属污染。

摘要:
本发明涉及一种高碳酸根掺杂碳羟基磷灰石吸附剂的制备方法及其应用,特别是具有高碳酸根掺杂的碳羟基磷灰石,其比表面积为300~400g/m<sup>2</sup>,且碳酸根与磷酸根比值1:3~5的高度掺杂碳酸根的羟基磷灰石。尤其是有机植酸为磷来源,以废弃物鸡蛋壳经煅烧后的原料为钙源,通过乙二胺为pH调节剂,柠檬酸为活化剂,采用水浴合成的方法,制备掺杂碳酸根羟基磷灰石前驱体,经溶胶-凝胶的熟化过程后,再在300~350℃条件下预氧化,然后再在450~600℃条件下煅烧,制备得到;本发明采用的原料来源于生活废弃物,成本低,同时制备的材料应用于土壤中重金属离子钝化修复,水体重金属离子处理,具有成本低,效果好。

摘要:
本实用新型涉及一种污水处理用网布,其包含表层,吸附层,底层,吸附层以“1X1”字形将表层和底层进行编织连接,表层以呈“11”字形编织,底层以“11”字形编织。本实用新型采用网布结构,在污水处理过程中,竖直方向上的经纱能够很好的与污水中的重金属进行接触,避免了传统织物由于重叠结构导致的与污水接触表面减少,导致吸附效果减弱的问题;内部的吸附层以“1X1”字形结构编织可以提高污水在网布内部的接触面积,同时利用外部表层和底层的截流作用,提高中间吸附层的吸附性能,达到表层和底层的一步吸附处理,然后利用吸附层的功能吸附作用,提升吸附效率;本实用新型用于水体中重金属离子的处理等领域具有广阔的应用前景。

摘要:
本实用新型涉及一种土壤修复钝化微胶囊,其特征在于,其包含芯层,中间层,保护层,且土壤修复钝化微胶囊由内到外依次为芯层,中间层,保护层,芯层和保护层之间具有中间层;保护层设置微孔。本实用新型采用多层结构设计微胶囊材料,避免单一的粉体吸附剂的难以收集,耐化学稳定性差等问题;同时通过采用碳酸钙进行表面保护层中的聚乙烯醇改性,并利用酸化对表面进行刻蚀,使保护层中碳酸钙溶胶,形成孔洞,提高微胶囊离子通道,利于土壤修复离子传导以及溶液传输;应用于环境土壤修复具有广阔应用前景。
