摘　　要：研究了Cl-、F-共存时Na型斜发沸石对废水中Cu2 + 交换量及废水深度净化率的影响规律 .实验结果表明 ,经NH4 Cl预处理 ,NaCl改性的Na型斜发沸石深度净化工业废水中Cu2 + 时 ,可以忽略Cl-、F-共阴离子及其温度通常变化对Na+ Cu2 + 水热交换量的影响 ,废水的深度净化率可达 97%以上 ,而Na型沸石的阳离子交换率仅达 8% .The properties of Na + Cu 2+ exchange on the Naform clinoptilolite in the model wastewater coexisting Cl - or F - anion were studied.The experimental results show ed that exchange properties of Na + Cu 2+ were not affected by the coexisting anion Cl - or F - on the Naform clinoptilolite as a whole.The deep purification ratio of Cu 2+ in wastewater is 97% or more,and the cation exchanga ratio of the Naform clinoptilolite is 8% only.So,for the purification of industral wastewater the Na...
