有机相中钼的测定,一般是将有机相中的钼反萃到水相后进行硫氰酸盐光度法测定。有人曾指出,在非均相反应的条件下,有机相中的六价状态的钼可用二氯化锡还原到五价,再以硫氰酸盐形成橙红色络合物,并萃入异戍醇中进行(?)色测定。但这些方法操作繁琐,而且不能测定有机相中的低价钼。根据低价状态钼可在碱性介质中转型的性质,本文提出先 The determination of molybdenum in the organic phase is generally carried out by thiocyanate spectrophotometry after stripping the molybdenum in the organic phase into the aqueous phase. It has been pointed out that under heterogeneous reaction conditions, the hexavalent molybdenum in the organic phase can be reduced to pentavalent with tin (II) chloride and then to an orange-red complex with thiocyanate and extracted into the Alcohol (?) Color determination. However, these methods are cumbersome to operate and can not determine the low molybdenum in the organic phase. According to the low-cost state of molybdenum transition in alkaline medium nature, this paper first
