Ion exchange of natural natrolite in melted salts

Abstract

In this research the  ion exchange potential of natrolite towards K+, Tl+, Cs+, Ca+2, Ni+2, Cu2+, and Co2+ in their melted salts was investigated. The effect of temperature, reaction time and zeolite to salt ratio on the exchange relation was studied. The exchange of Ca2+, Ni2+, Cu2+, and Co2+ was negligible and was equal to 2.59, 6.29, 3.14 and 5.04 percent respectively whereas the exchange of K+, Tl+, Cs+ was relatively high and equal to  82.36, 66.67 and 42.98 percent respectively.
