Adsorption Properties and Dynamics of Potassium in Mother Liquor B on Ion Exchange Resin

Abstract

Abstract: Adsorption properties and kinetics for of the removal of K+ from mother liquor B on BK001 type ion exchange resin were investigated by studying the effects of temperature, concentration and resin particle size on K+ static exchange. At 303 K and 333 K, the adsorption behavior of K+ on the resin obeyed Langmuir isothermal adsorption. The exchange process was mainly dominated by particle diffusion; the apparent activation energy was 35.1 kJ/mol, the reaction order was 1.389, and the apparent frequency factor was 8439 min-1.

Key words: ion exchange resin, adsorption property, kinetics, mother liquor B, K+
