- Аннотация: A new anion exchanger for ion chromatography bearing an N,N-dimethylhydrazine functional group was synthesized by chloromethylation followed by the amination of a copolymer of styrene and divinylbenzene with a crosslinking degree of 50%. Its chromatographic properties were studied in a two-column mode of ion chromatography with conductometric detection. The anion exchanger obtained is characterized by better selectivity and efficiency than ion exchangers bearing alkylammonium functional groups, namely, trimethylamine, triethylamine, N,N,N',N'-tetramethyldiaminomethane, N,N,N',N'- tetramethylethylenediamine, and pyridine. Addition of p-hydroxybenzonitrile in the eluant improved the shape of the peak of the nitrate ion and allowed the simultaneous determination of fluoride, chloride, nitrate, phosphate, and sulfate ions.
