Synthesis and chromatographic
characteristics of carboxylic cation-exchangers based on alkyl silica
dynamicallymodified with
hydrolysed maleinised linseed oil
Abstract
New carboxylic cation exchangers were prepared by
dynamic modification of octyl- and octadecyl – silicawith hydrolyzed maleinised linseed oil (HMLO). The approximate amount of loaded HMLO and ion exchange capacity were evaluated. The
selectivity of the separation of alkali, alkaline-earth and ammonia cations was
investigated by ion chromatography with conductimetric detection. The
comparison of ion-exchange selectivity of prepared ion-exchangers and some of commercial carboxylic cation
exchange analogues is performed.
