摘要: The macroporous anion exchangers with long-chained cross-linking agents were investigated
for the tungsten recovery from salt solutions. The physical-chemical characteristics of
these sorbents were studied by means of sorption-desorption experiment aswell as electron
and IR-spectroscopy. The anion exchangers on the basis of macroporous copolymers of
methylacrylate and divinyl-ester of diethyleneglycol or tetravinyl-ester of pentaerythritol
possess the exchange capacity to tungsten 2-5 times greater than the porous anion
exchangers on the basis of styrene and divinylbenzene, therefore they can be used for
selective tungsten recovery from complex salt solutions.
