A Simple method for simultaneous determination of ~ Co;~ Co;and ~ zn in marine organisms was proposed. Cobalt;iTon and zinc in medum of hydrochloric acid are absorbed on anion resin and purified by passing the 0.18N HF-8N HC1 solution through the resin bed. Then cobalt;iron and zinc are eluted from the resin respectively and precipitated for counting. The recoveries of cobalt;iron and zinc are 88.27±5.38;;97.05±2.09;;and 89.30±4.95;;respectively. The decontamination effect of this method is better;Several marine organism samples were analyzed by this method.
