Abstract

Exchange kinetics of some transition metal ions on tin(IV) arsenosilicate has been studied at various temperatures under particle diffusion controlled conditions. Various useful kinetic parameters such as self-diffusion coefficient (Do), energy of activation (Ea) and entropy of activation (ΔS*) have been calculated and compared with other similar materials.

Abstract

Кинетику обмена ионов некоторых переходных металлов на арсеносиликате олова (IV) исследовали при различных температурах и при условии контроля диффузии частиц. Были рассчитаны различные важные кинетические параметры такие, как коэффициент самодиффузии (DO), энергия активации (Ea) и энтропия активации (ΔS*), которые сравнивались с величинами для подобных материалов.
