摘要: An equilibrium study of the Na+Cs+H+ ion exchange on γ-titanium phosphate has been carried out. Isotherms for have determined and phases formed during identified. Over entire composition range, exchanger greatly prefers cesium to sodium. For 0–25% exchange, sodium 25% conversion were found be at when ratio sodium-cesium concentration solution is 100:1. The constant determined. When 50% reached by addition stoichiometric amount base, a solid barHNaxCs1−x formula (with varying with composition) formed. substitution process Na+Cs+ in phase A diagram ternary system given. results are compared those previously obtained Na+H+ Cs+H+ binary systems. mechanism proposed.
