P538是一种单烷基磷酸萃取剂(ROP(O)(OH)_2,R=C_(12)-C_(18)),已见其基本萃取性能的报道和萃取除Fe(Ⅲ)的应用。本文研究了它在煤油-硝酸盐介质间的分配平衡。并讨论了萃取机理。
P538 is a monoalkylphosphoric acid extractant (ROP (O) (OH) 2, R = C 12-C 18). It has been reported that its basic extraction performance and extraction application of Fe (Ⅲ) . This paper studies its distribution equilibrium between kerosene and nitrate media. And discussed the extraction mechanism.
