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 Naform clinoptilolite is more useful than other methods.
