Removal of arsenic from solutions by extraction of amines

Abstract

During experiments is considered the extraction of anions salts and acids (AsO2 –, SCN–, ClO4 –, Br–, HSO4 –, BrO3 – from water solutions by alkyl amines with various degree of replacement on the atom of nitrogen with the length of hydrocarbon radical C8-C18 in organic phase of extenders: anizol, furan, benzene, cyclohexane. Identified dependence of factor of distribution on length of hydrophobial radical and type of polar group amines, the nature of extracted anions and extenders.
