| Abstract: | A new methed for determination of trace amounts of lead is described. In 0. 01 mol/LHAc-NaAc solution, lead-glyoxalic acid thiosemicarbazone (GATSC) complex produces a very sensitive reduction peak. The peak potential of the wave is -0. 63V (vs. SCE). The change of tile peakheight for lead concentration is liner in the range of 1. 0×10-8￣3. 00×10-7 mol/L. The detectionlimit is 2×10-9 mol/L. The method has been satisfactorily used for the determination of traceamounts of lead in water. |
