摘要：
Separation of molybdenum in the form of anionic thio complexes from weakly alkaline aqueous solutions of sodium and ammonium tungstates with several weakly basic anion exchangers was studied. Macroporous anion exchangers AN-20, AN-221, and AN-511 are optimal and can be used for efficient sorption removal of molybdenum from concentrated tungstate solutions. The influence of pH and temperature on this process was examined.
