摘要
利用由河北赤城县金矿尾矿合成的 13X沸石 ,进行了去除废水中Ni2 + 的实验研究 ,探讨了沸石用量、粒径、废水 pH值、初始浓度、反应时间、温度等因素对Ni2 + 去除率的影响。实验结果表明 ,当溶液pH =5～ 8,C°2 + Ni =5 0～ 2 5 0mg/L范围内 ,按Ni2 + /沸石质量比 1∶4 0进行吸附 ,Ni2 + 的去除率可达
The 13X zeolite is synthesized by the tailing of goldmine in Heibei Chicheng.The treatment of nickel containing waste water with 13X zeolite were experimentally investigated.The results show that the nickel removing ratio is greater than 98% in the condition of pH=5～8,Ni/zeolite=1∶40, and the mass concentration of NJ 2+ = 50～250mg/L.
