摘要
用丁基苯并噻唑亚砜(用M表示)、MSO作萃取剂,在盐酸介质中萃取钯。结果表明:用煤油作稀释剂,M与MSO组成的体系对钯有较好的协萃能力。本文考察了协萃剂浓度、水相中盐酸浓度、萃取时间、相比对钯萃取率的影响,测定了钯的饱和容量。本文还考察了氨水、KSCN反萃钯的性能。
In hydrochloric acid medium, synergic extraction of palladium（Ⅱ ） is studied by butyl- benzothiazole sulfoxide（simplified form as M） and MSO, and the synergic system consisting of M-MSO can extract palladium （Ⅱ） efficiendy . In the paper, synergic reagents concentration,hydrochloric acid concentration in water phase, extracting time , phase ratio are studied respectively. Saturated capacity of palladium（Ⅱ）is determined . Performances of stripping palladium（Ⅱ） are studied with NH3·H2O and KSCN.
