Atizetmuller和Buchtela等采用醋酸纤维素膜(CAM)作支持体研究了希土与α-HIBA体系中的电迁移行为。本文在文献[6]的基础上,对Eu的电迁移行为的影响因素:电解质浓度、端电压、离子强度、电解质的pH、电迁移时间、冷却水温度、原始料液的酸度和外来离子等进行了研究。还测定了采用推荐程序时Eu的电迁移速率、Eu与α-HIBA一级络合物的稳定常数。 Atizetmuller and Buchtela et al. Used cellulose acetate membrane (CAM) as a support to study the electromigration behavior in both rare earth and α-HIBA systems. Based on the literature [6], the factors affecting the electromigration behavior of Eu are: electrolyte concentration, terminal voltage, ionic strength, pH of electrolyte, electromigration time, temperature of cooling water, acidity of raw material solution and foreign ions Were studied. The electromigration rates of Eu and the stability constants of Eu and α-HIBA primary complexes were also determined.
