摘　　要：TPPC在0.08mol/L CH_3COONa和0.4mol/L CH_3COOH(NaAc-HAc下同)底液条件下,在电位 —1.57 V(υs.SCE)附近产生一尖锐的导数波,峰高在3.7×10^(-6)～5.6×l0^(-5)mol/L范围内呈线性关系.同时,讨论了极谱波的性质及电极反应机理.In a supporting electrolyte of 1 mol/L CH3COONa and 5 mol/L CH3COOH, a sensitive adsorptive wave of 3, 3 ' -tetramethylene-bis-( 1-phenyl-5-pyrazolone-4-carboxylicester) (TPPC) has been obtained in single sweep oscillopolarography. The peak potential of the wave is about - 1. 57 V(vs. SCE). The peak height of second derivative wave of the TPPC is linear in the range from 3. 7 × 10-6 mol/L to 5. 6 × 10-5 mol/L. The adsorptive behaviour of the TPPC has been studied by several electrochemical methods. The wave has been proved to be an adsorptive wave. The mechanism of this electrode reaction has been discussed.
