| 摘 要： | 研究了采用ZnCl2化学活化法制备的污泥含炭吸附刺去除水溶液中Cu^2＋的效果，考察了溶液pH值、吸附时间、吸附剂用量和Cu^2＋浓度等对去除率的影响。实验结果表明，污泥含炭吸附剂对Cu^2＋具有较强的吸附性能，吸附平衡时间约为1h；pH值是影响吸附的主要因素，实际应用中一般控制在pH=5．0；Cu^2＋的浓度不宜过高，为了达到较好的去除效果，实际应用中吸附剂用量一般不能低于2g／100mL溶液。

| Abstract: | This paper studied the effect of Cu2+ removing by sludge carbon adsorbents which was made by a technics of ZnCl2 chemical activation.Thus the effects of the initial pH value of the solution,the adsorption time,the dosage of the adsorbent,and the initial concentrations of Cu2+ in the solution on the removal rate were investigated.The feasibility to recover Cu2+ in aqueous solution using the activated carbon adsorbents had good adsorption capability for Cu2+,adsorption equilibrium time was about one hour,the ... |
