| 摘 要： | 采用聚合硫酸铝对杭锦2#土进行改性并制备吸附剂,研究改性土对生活废水中磷酸根的吸附性能,讨论了吸附剂用量、磷酸根浓度、溶液pH值、温度对吸附容量的影响及其吸附动力学特征.结果表明,改性杭锦2#土的投加量增大,磷的去除率增加;初始磷浓度增加,去除率下降,吸附平衡时间增加;溶液pH值为2.5时改性土对磷酸根的去除效果最好;温度升高,吸附容量减小,表明该吸附反应为放热反应.改性杭锦2#土对磷酸根的静态吸附等温线可以用Langmuir方程表示,吸附动力学符合拟二级反应方程.

| Abstract: | Polysulphate Aluminium was used to modify Hangjin 2# clay-improved adsorbent.The effect of adsorbent,phosphoric acid radical concentration,pH value of solution and temperature on adsorption performance for phosphoric acid radical in domestic sewage had been studied.Furthermore,its dynamic characteristics were studied as well.The results showed that the phosphorus removal was increased with the increasing of Hangjin 2# clay-improved adsorbent amount;the phosphorus removal was decreased and adsorption equilib... |
