本文研究了用季铵盐从碳酸铵、硫酸铵碱性溶液中萃取钼的机理。用紫外吸收光谱、紫外吸收光谱—等摩尔系列法和喇曼光谱测定研究了钼与过氧化氢的络合作用及其摩尔比。指出该络合物的稳定性与溶液pH值之间的关系。采用等摩尔系列法和饱和萃取法初步确定了萃合物的组成,对影响萃取的因素也进行了研究。 In this paper, the mechanism of extracting molybdenum from ammonium carbonate and ammonium sulfate alkaline solution by quaternary ammonium salt was studied. The complexation of molybdenum with hydrogen peroxide and its molar ratio were studied by ultraviolet absorption spectroscopy, ultraviolet absorption spectroscopy - equimolar series and Raman spectroscopy. The relationship between the stability of the complex and the pH of the solution is indicated. The equimolar series method and the saturation extraction method were used to determine the composition of the extract, and the factors affecting the extraction were also studied.
