二-(2-乙基己基)磷酸-熔融石蜡对锰的固液萃取研究
Study of solid-liquid extraction of manganese with di(2-ethylhexyl)phosphoric acid into molten paraffin wax
摘要
Abstract
The extraction behavior of manganese with di(2-ethylhexyl)phosphoric acid(P204,D2EHPA) into molten paraffin wax has been studied. The effects of pH, D2EHPA concentration, phase ratio, manganese ion concentration, D2EHPA concentration, extraction time, temperature etc. On the extraction percentage are discussed in details. The extraction reaction is given to be Mn2+ + H2 A2 = MnA2 + 2H+. The extraction thermodynamics data are determined. The study has indicated that the iron ion can be separated from manganese ion in the pH range of 0. 5 to 1. 2.关键词
