Inductively coupled plasma spectrometry was used to study of enriching and separating trace Au, Pt, Pd, and Ir by using poly(vinyl ethylenediamine). The performance, rate and mechanism of the chelate resin enriching the trace elements were investigated. The anal. of samples have been performed with satisfactory results.
