用Bjerrnm-calvin pH滴定技术,在35℃、用3:1二氧六环:水溶液及离子强度恒定(0.1MKNO3)的条件下测定了反式5-异戊基2-羟基二苯甲酮肟萃取剂与质子、铜(Ⅱ)、铁(Ⅲ)、钴(Ⅱ)、镍(Ⅱ)、锌(Ⅱ)的络合稳定常数.并测得反式3-仲丁基2-羟基二苯甲酮肟和反式5-仲丁基2-羟基二苯甲酮肟萃取剂与质子、铜(Ⅱ)的络合稳定常数.

Stability constants of anti-2-hydrozy-5-isoamyl-benzophenosime eatraotants with proton. copper (Ⅱ),iron (Ⅲ),cobalt (Ⅱ),nipkel(Ⅱ),zine (Ⅱ) were determined by using the Bjerrnm-Calvin pH titration technique. The measurements were carried out at 35±0.1℃ in 3:1 dioBane:water at constant ionic strength (0.1 M KNO3).Stability constants of anti-2-hydrozy-3-sec-butyl-benzophenogime and anti-2-hydrozy-S-sec-butyl-benzophenosime eztraotants with proton,popper(Ⅱ) were also obtained.
