Synthesis,Properties and Adsorption of Strong Base Weak Acid Amphoteric Resins

Wu Yan

Abstract

A series of macroporous copolymer were synthesized by suspension copolymerization with toluene and cyclohexane as diluent. The effects of crosslinking agent and mixed diluent on structure properties such as porosity,pore volume,average pore diameter and specific surface area were investigated. The adsorption and separation of amphoteric resins is discussed by the comparison of adsorption isotherms of citric acid at different temperatures.
