通过水热合成法制备了茶叶渣负载羟基磷灰石复合材料（简称HAP-T）,并利用傅立叶变换红外光谱仪对其进行表征。研究了HAP-T对Mn^2＋吸附的时间、pH、温度、用量等因素。结果表明：在pH为4.5、温度为40℃的条件下吸附90 min,HAP-T对Mn^2＋吸附效果最佳,吸附率达到98.76%,同时HAP-T对Mn^2＋的吸附受温度影响不大。

The modified waste tea by hydroxyapatite was prepared by the method of hydrothermal synthesis and the flame work and structure were characterized by means of FT-IR. The effect of absorbing time, pH, temperature and quantity of absorbent on the adsorption rate to Mn ion were studied. Results showed that The adsorption rate of HAP-T for Mn ion can achieve up to the best result of 98.76 percent when pH is 5-6 and temperature is 40 ℃ at 90 rain. Meanwhile the adsorpti...
