In a supporting electrolyte containing 6×10~(-5)M Alizarin red S, 0.2 M NH_3-NH_4Cl,at pH 8.2-8.6, three adsorptive complex waves of germanium-Alizarin red S have been obtained bysingle-sweep polarograph. The most sensitive one among them is at Ep=-1.130 V (SCE). Thecompositions of the complexes and the mechanism of electrode processes were studied in detail.
