用BП-1型阴离子交换剂从PH=3～4的工艺溶液中吸附钼时,出现了溶液中所含铁和铜杂质与钼一起转向离子交换剂的现象。随后采用PH≈0.75的酸化水洗涤饱和的树脂,可以分离50-60％的铁和98-100％的铜。本文研究了PH=3～4和酸度更大时吸附钼的规律性,旨在确定降低杂质吸附性的可能性。研究所用B(?)-1×10/25型阴离子交换剂含有10％联乙烯苯, Adsorption of molybdenum from a process solution of PH = 3 to 4 with BП-1 type anion exchanger led to the phenomenon that iron and copper impurities contained in the solution were diverted together with molybdenum to the ion exchanger. Subsequent washing of the saturated resin with acidified water at pH ≈ 0.75 leads to the separation of 50-60% iron and 98-100% copper. In this paper, the regularity of adsorption of molybdenum with pH = 3-4 and higher acidity is studied to determine the possibility of reducing the impurity adsorption. B (?) - 1 × 10/25 type anion exchangers used in the research contain 10% divinylbenzene,
