摘要: Abstract The voltammetric method of Cr(VI) determinations in the flow system, based on combination selective accumulation product reduction HMDE and a very sensitive chromium determination presence bipyridine [Z. Gao K.S. Siow, Electroanalysis 8 (1996) 602] is proposed. calibration graphs were linear from 3×10 −9 to −8 5×10 −10 mol l −1 for times 120 600 s, respectively. relative standard deviation (R.S.D.) was 6.5% ( n =5) concentration 1×10 time s. influence foreign ions commonly present water samples presented. Validation made by comparison results analyses tap another electrochemical recovery test river mineral water.
