摘要
用三氯化铁改性的红壤作为吸附剂对水中的磷进行吸附,考察了吸附剂吸附过程中时间和温度对吸附的影响。实验结果表明,改性红壤对磷的吸附是一个准二级反应过程;整个吸附过程符合Freundlich等温线,25℃时对磷的最大吸附容量为428.4mg.g-1。
Red earth（RE） was modified with FeCl3 for the removal of phosphorus in water.The effects of contact time and temperature on the adsorption of phosphorus in adsorption progress were investigated.The adsorption of modified RE on phosphorus followed pseudo-second-order kinetics.This process could be described by Freundlich model,and the maximum adsorption capacity for phosphorus was 428.4 mg·g-1 at 25℃.
