【Abstract】 In this paper the conditions of enrichment of the traces of Cu 2+ and Zn 2+ by SL-401 multi-amino-carboxylic chelating resin with the group of -CH 2N(CH 2COOH)CH 2CH 2N(CH 2COOH) 2 were studied. A new method of the FAAS determination of the traces of Cu 2+ and Zn 2+ in biological samples by separation with SL401 resin was established. It was used for the determination of the traces of Cu 2+ and Zn 2+ in cattle or pig heart and liver biological samples respectively and the satisfactory results were obtained.更多还原
