Description
The possibility for using magnesium-ammonium phosphate as a sorbent to separate Cs+, Rb+ and K+ ions is estimated. The sorbent composition is close to NH4MgPO4x6H2O. Sorption isotherms have been removed under static conditions at 293±2 K separately for Cs+, Rb+ and K+ ions. Determination of the separation coefficients of these Cs+-Rb+ and Rb+-K+ ion pairs (the ratio of the ions separated in the initial solution varies from 1:1 to 1:10) during their sorption by NH4MgPO4x6H2O phosphate gave the following estimation of the values measured: PCs-Rb=(30-156) and PRb-K=(7-15). Taking into account high values of the separation coefficients and good reversibility of the ion exchange process NH4+↔Me+(Me+=Cs+, Rb+, K+) by phosphate and with the struvite structure, it is possible to recommend this sorbent for practical application
