EXCHANGEABILITY OF ADSORBED CATIONS AS INFLUENCED BY THE DEGREE OF SATURATION AND THE NATURE OF THE COMPLEMENTARY IONS WITH SPECIAL REFERENCE TO TRACE CONCENTRATIONS

Abstract

Radio-active K and Sr were used to study the exchangeability of traces of these ions from Amberlite IR-1. With decreasing K content, the exchangeability of K decreases when Na is the complementary ion but increases when Ba is the complementary ion. In the same way the exchangeability of Sr decreases with falling Sr content when combined with Na, and increases when combined with Ba.
