弱酸强碱两性树脂解吸动力学的研究

The Study of Elution Kinetics On Amphoteric Resin Containing Carboxyl and Quaternary Nitrogen Groups

本文采用浅床解吸法对离子在弱酸强碱两性树脂相内的扩散进行了研究．结果表明：阳离子所带电荷越多．其粒内扩散系数就越小，阴离子体积越大．电荷多．则粒内扩散系数也越小。

The diffusion of ion inside an amphoteric resin containing carboxyl and quaternary nitro-gen groups has been researched by shallow - bed elution method.The conclusions have beenmade. The higher the charges on a cation and the bigger of an anion size, the smaller the diffusioncofficients inside the resin.
