| Abstract: | A new method of adsorptive stripping voltammetry-eatalytiepo larographic hydro- gen wave (AdSV-CPHW) based on the flow injection analysis (FIA) has been studied for the determination of trace platinium. High sensitivity and fast determination were achieved by combination of the advantage coming from the AdSV-CPHW and FIA. The conditions were optimized with respect to the supporting electrolyte composition, flow rate, injection volume, preaeeumulation potential and adsorptive time etc. The samples of organic complex, biomaterial and minerals were successfully tested. |
