摘　　要：在0.05mol/L H_3PO_4,0.0016%CPB介质中,Au-QBTU产生一灵敏的吸附波,峰电位-0.63V(vs.SCE),1.5次微分峰电流与金的浓度在5.0×10^(-8)～1.0×10^(-6)mol/L范围内有良好的线性关系。本文对电极过程、反应机理等进行了探讨。In a solution of 0. 05mol/L H_3PO_4-0.0016% CPB, Au-QBTU gives a sensitive adsorption wave, with the peak potential at -0. 63V(vs. SCE). The Change of peak current of the 1. 5 order derivative wave with the concentration of Au is linear in the range from 5. 0×10~8 to 1.0×10^(-6)mol/L. The reaction mechanism and electrode process have been discussed.
