Synthesis and chromatographic characteristics of carboxylic cation-exchangers based on alkyl silica dynamicallymodified with hydrolysed maleinised linseed oil


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.
