摘要
将铁观音废茶经过处理后作为吸附剂,并进行FT-IR表征。使用该吸附剂对水相中的UO22+进行静态吸附实验,考察pH、温度、吸附时间、初始浓度、吸附剂用量、离子强度吸附性能的影响,通过对实验结果的动力学模型、吸附等温模型拟合推断吸附机理。
Powdery adsorbent was prepared by pretreating the raw material, the scrap of Tieguanyin Tea. Analyzing the FT-IR characterization of adsorbent. Then, the adsorption properties of uranyl ion on this adsorbent were studied, the influence of pH, Temperature, adsorption time, initial concentration, adsorbent dosage and ionic strength on adsorption were discussed. And the adsorption mechanism was inferred by fitting experimental results with dynamic model and adsorption isotherm model.
