Abstract

Preconcentration/atomic absorption spectrophotometric determination of trace metal ions was investigated with xanthate or dithiocarbamate immobilized silica gels as the chelating functional groups. The preconcentration and determination of trace amounts of palladiu m(III), silver(I), platinum(IV) and gold(III) was performed with good precision.
