以5mmol／L铬酸钠-0．5mmol／L十四烷基三甲基溴化铵为背景电解质溶液，研究了33种阴离子的有效迁移率与极限当量电导及正构羧酸的有效迁移率与碳数的关系。结果表明阴离子的有效迁移率随极限当量电导的增加而增加；C2～C7的正构—元羧酸和C2～C10的正构二元羧酸同系物的有效迁移率的倒数与碳数呈正比，线性相关系数大于0．997。
Taking 5 mmol / L sodium chromate-0.5 mmol / L tetradecyltrimethylammonium bromide as the background electrolyte solution, the effective mobilities of the 33 anions and the limiting equivalent conductances and the effective mobilities of the normal carboxylic acids Relationship with carbon number. The results show that the effective mobility of anions increases with the increase of the limiting equivalent conductance. The reciprocal of the effective mobility of C2 ~ C7 normal-carboxylic acids and C2 ~ C10 ortho- dicarboxylic acid homologues is proportional to the carbon number , Linear correlation coefficient greater than 0.997.
