Abstract: This paper describehe the determination of Se(Ⅳ) in 0.5 mol/L HCl-4μg/mL Cu(Ⅱ) solution by title metthod. The height of the strpping peak can be deter-mined at -0.54 or -0.63 V (vs. SCE), determined concentration range is 0.04- 20ng/mLof Se, and the pre-electrolytic potential, is -0.25 or -0.35 V. The detection limit is pg/mLlevel. The relative standard deviation is 7.1% at the concentration of Se(Ⅳ) 0.14 ng/mL.The reaction process and behavior of the cathodic stripping peaks have been studied and discussed.
Key words: Cathodic stripping voltairmetry, Deleron, minatiSelcnium(Ⅳ)
