摘要：
Preparation conditions of composite ion-exchanger based on stannic molybdophosphate (SMP) and poly-acrylamide (PAA) have been described. Batch distribution coefficients for some ions were investigated at 25 C. Sodium ion exchange capacity and breakthrough curves of cesium and strontium ions have also been determined. The results obtained from the experiments showed that the selectivity of SMP-PAA for cesium and strontium was greater than for other ions. Adsorption amounts of both ions were higher than 99% in demineralized water and their uptake rate were relatively rapid.
