三正辛胺(TOA)萃取色谱法分离金属离子的研究已有报道,但分离钨、钼的研究还未见报道,本文根据 TOA 的石油醚溶液从水相中萃取钼、钨行为的差异,试验了以大孔树脂负载 TOA 的萃取色谱法分离钨、钼的条件。试验表明,在确定的条件下,能用于钢样中钨、钼的分离与测定,结果令人满意。
However, the research on the separation of tungsten and molybdenum has not been reported yet. According to the differences of the extraction behavior of molybdenum and tungsten from the aqueous phase of TOA in petroleum ether solution, The conditions for the separation of tungsten and molybdenum by extraction with macroporous resin TOA were studied. Experiments show that under certain conditions, it can be used for the separation and determination of tungsten and molybdenum in steel samples with satisfactory results.
