Abstract
The possibility of using macroporous methacrylate-based low-capacity ion exchangers in the separation of cations of alkali, alkaline earth, transition and heavy metals was tested. The separation conditions were optimized with respect to the composition of the eluent (content of ethylenediamine, tartaric acid, organic solvent and pH). The retentions of cations on methacrylate ion exchangers were compared with those on derivatives of styrene-divinylbenzene and silica gel. The detection limits obtained using the usual apparatus and method were 2.5 · 10 −8g.
