摘要： 通过等摩尔系列法、摩尔比法、饱和法以及有机相的红外光谱等研究了伯胺N1923从中性溶液和伯铵盐从酸性溶液萃取Mo(Ⅳ)的机理,结果表明,伯胺从中性溶液萃取Mo(Ⅳ)按溶剂化历程进行,伯铵盐从酸性溶液萃取Mo(Ⅳ)是阴离子交换反应。

Abstract: The extraction of Mo(Ⅵ)by primary amine(abbreviated as N1923 or RNH2)in kerosene has been investigated.The effects of pHof the aqueous phase and temperature on this extraction process have been examined. The composition of extracted compound has been determined by equimolar series method, molar ratio method and saturation experiment.The infra-red spectra of the organic phase have also been studied.The mechanism of extraction is discussed.

Key words: Primary amine, Molybdenum, Extraction mechanism, Extracted compound
