| Abstract: | A sensitive differential adsorptive wave of zinc (Ⅱ)-alizarinviolet complex was obtained by using linear sweep polarography in B-R buffer (pH=9.96) containing 0.1 mol/L KCl and 0.02% alizarin violet in alcohol. The peak potential was -1.27 V (vs. SCE). The peak height had a linear relationship with the concentration of zinc from 5×10-8 to 2×10-6 mol/L. The detection limit was 5×10-8 mol/L. The method has been applied to the determination of Zn (Ⅱ) in hair samples with satisfactory results. |
