Abstract: In a supporting electrolyte containing 2?10-4M DMG, 0.025M Na2B4O7 at pH=9.4, a sensitive adsorptive complex wave of copper-DMG was obtained by using single-sweep polarography. The peak potential is -0.34V(vs.SCE). The peak height changes linearly with the concentration of copper in the range of 5?10-8 to 3?10-6M. The method has been applied successfully for the trace copper determination in waste water.
