摘　　要：本文报导了镓-茜素络合剂极谱络合吸附波产生的条件及其电极过程机理的研究.Sommer等曾报导了镓-茜崇红S的脉冲极谱行为[1]。莫茂生也曾提到镓-茜素红S的单扫导数波的检测下限达0.01g/ml的镓[2].我们在研究稀土-茜素络合剂体系极谱行为的基础上[3],还得到了镓-茜素络合剂的络合吸附波。In a supporting electrolyte containing 3 × 10^(-5)M alizarin complexone, 0.2M HAc-NaAc, at pH = 3.6, a sensitive adsorptive complex wave of gallium-alizarin complexone was obtained by using single-sweep polarography. The peak potential is - 1.14V (Ag/AgCl). The change of peak height with the concentration of gallium s linear in the range of 1×10^(-7) to 1 × 10^(-5)M The electrode processes of the adsorptive complex wave may be presented as follows.
