Separation of «MgCl2-HCl» and «CaCl2-HCl» mixtures by means of low basic anion exchangers such as AN-221, AN-251 in non-exchange conditions

Abstract

Separation of chloride-containing mixtures of electrolytes such as «MgCl2 - HCl» (0,01 M: 0.01
M) and the «CaCl2 - HCl» (0.01 M: 0.01 M) by means of the low basic anion exchangers (AN-221,
AN-251) in non-exchange conditions was carried out. Concentration of hydrochloric acid for the «CaCl2 -
HCl - AN - 251 in HCl-form» system in sorbent phase was detected. It was found that the using of
systems with the low basic anion exchangers in non-exchange conditions allows completely to separate
the chloride-containing mixtures of electrolytes such as «MgCl2 - HCl» (0,01 M: 0.01 M) and the «CaCl2
- HCl» (0,01 M: 0.01 M) on a thin sorbent layer .
