摘要：
A method of group separation and preconcentration of trace amounts of some heavy metals using thionalide loaded Bio Beads SM-7 resin has been elaborated. Cadmium, Cu and Fb are quantitatively retained on th: sorbent at pH 5.0. Cobalt, Ni, Zn and also Cd are retained at pH 7.5. The retained elements are eluted from the sorbent with 2 mol l(-1) hydrochloric acid. The method was applied to the analysis of tap water. The determination of the elements was carried out by atomic absorption spectrometry with flame atomization.
