| 摘 要： | 为了用吸附法去除废水中铜离子,本实验研究了绿色吸附剂小球藻粉对Cu^2＋离子的吸附特性。结果表明：小球藻粉吸附Cu^2＋的吸附平衡时间为90 min,在p H为5,吸附温度为30℃,Cu^2＋初始浓度为200mg/L的条件下,Cu^2＋吸附效果最好,去除率达99.99%。Freundlich方程比Langmuir方程更好地描述小球藻粉吸附Cu^2＋平衡吸附行为。该吸附符合二级动力学方程并且为自发、放热的物理吸附过程。利用小球藻粉去除废水中Cu^2＋是可行的。

| Abstract: | The copper ion adsorption characteristics by green adsorbent chlorella powder were studied experimentally to remove copper ions from aqueous solutions. The results show that the optimum conditions are an initial p H of 5,adsorption time of 90 min,and temperature of 30℃. When copper ion initial concentration is200 mg / L,the removal efficiency is 99. 99%. Both the Freundlich model and the Langmuir model can describe the copper ion equilibrium data,with the Freundlich adsorption isotherm providing better agreement with the data. The adsorption rate can be well fitted by pseudo-secondrate model,is spontaneous and exothermic physical adsorption process. Chlorella powder can be used to remove copper ions from aqueous solutions. |
