摘要
根据用柠檬酸盐作流动相时,ReO_4^-在PRP-S柱上保留时间出现异常现象,本文提出用HPLC法测定高铼酸根与柠檬酸、酒石酸和草酸形成的易变配位化合物的稳定常数,在水溶液中分别为123、35.6和45.1。
A HPLC method is proposed for determing the stability constants of some labile complexes
formed by perrhenate with citrate, tarate, and oxalate according to the abnormal retention time
of ReO^4^- on colum of PRP-s using a mobile phase of citrate. In aqueous solution the stability
constants of the three labile complexes are respectively 123, 35. 6, and 45.1.
