Abstract

Abstract: In a supporting electrolyte containing potassium hydrogen phthalate(KHP)at pH 3.3,a sensitive derivative peak of Cu(I)-allylthiourea(ATU)complex was found by single-sweep oscillopolarography. The peak shows a potential of-0.32V(vs.SCE)and its heightis linearly proportional to the concentration of Cu in the range of 0.002 to 0.12μg/mL.The mechanism of the wave formation has been discussed. It is confirmed that the peakwave is the adsorptive-complex wave of Cu(I)-ATU.

Key words: copper, allylthiourea, polarography, microdetermination
