摘要
在静态和动态条件下 ,研究了改性斜发沸石对工业废水中重金属离子Cu2 + 、Zn2 + 、Cd2 + 、Pb2 + 的吸附。结果表明 ,改性斜发沸石对重金属离子有较好的吸附 ,pH值是影响吸附的主要因素。采用 1mol/LHCl+NaCl(V/V =1∶1)混合溶液作为斜发沸石的再生剂 ,可使其重复再生使用。
The adsorption capability of natural clinoptilolite can be improved by modification.The adorption effect of modified clinoptilolite to heavy metal ions from waste water such as Cu 2+ ,Zn 2+ ,Cd 2+ and Pb 2+ was studied under static state condition and dynamic state condition.The results showed that modified clinoptilolite had better adsorbability for heavy metal ions,moreover pH value of solution was the main factor affecting adsorption.The mixed solution of 1mol/L HCl+NaCl( V/V Z]
