Investigation on the Polarographic Wave of Zinc-Arginine Complex

LUO Deng bai *, QIN Yin feng, XIANG Fu, QING Xiao fang (Department of Chemistry, South Central Univerity for Nationalities, Wuhan, 430074)  
A sensitive adsorptive polarographic wave of zinc arginine complex with E p=-1.27 V(vs.SCE) has been observed by using single sweep polarography in ethanolamine hydrochloric acid buffer solution (pH 9.5) containing 5.8×10 -3 mol/L arginine. The peak height is linearly proportional to zinc concentration over a range of 1.0×10 -7 ~ 3.0×10 -6 mol/L. This method was applied to the determination of trace amounts of zinc in hair and waste water. The behaviour of the polarographic wave has been briefly discussed.
