Unforseen factors influencing Fe(III)-containing cations sorption on strongly basic anion exchangers

Abstract

The sorption and partial destruction of the Fe(III)-containing compounds in the aqueous medium in strongly basic anion exchangers AV-17 and Varion-AD phase have been investigated. It is shown that partial destruction of the Fe (III) compounds in acidulated water (pH = 2) and in K2SO4, Fe2(SO4)3 solutions takes place. With increasing of temperature up to 50°C, the desorption degree of the iron ions from polymer phase decreases.
