- Abstract
Potassium nickel hexacyanoferrate, KNiFC, was incorporated in the porous matrix of zeolites by successive impregnation with Ni(NO3)2 and K4Fe (CN)6.1 CFC and PFC exchangers were first prepared by impregnating the potassium nickel hexacyanoferrate into the clinoptilolite and the synthetic P zeolite, respectively. Ion-exchange isotherms and breakthrough curves were plotted. Results showed that the CFC sorbent is suitable for removal of Cs+ where PFC is more suitable for Sr2+. Negative effect of Na+ as a competing ion in these exchangers was less than in the parent zeolites. Isotherm plots fitted the Langmuir equation.
