In the 0.1M acetate buffer solution, at pH 5.9, alizarin complexone exhibits a reversible adsorptive prewave. On the surface of DME, the adsorption of alizarin complexone obeys Frumkin adsorption isotherm. In the same buffer solution, when the thulium was added, a sensitive adsorptive complex wave of thulium‐alizarin complexone has been obtained by single‐sweep polarograph. The composition of the complex and the mechanism of electrode processes were studied in detail.
