A. H.) has been mainly measured with a spectro - photometer and analyzed by colorimetrical method, i. e., by XYZ color system of C. I. E. In process of discoloration, some interesting behavior is noticed at the concentrations of coagulation value and of critical micelle formation of D. A. H. It has been found out, moreover, that the absolute measurement of colorimetrical determination of D. A. H. due to chromaticity can be applied with satisfactory accuracy at the concentrations of less than 4 mM/l. Discoloration of Malachite green oxalate by Sodium dodecyl sulfate has also been measured and its results are briefly reported in addition., Article, 信州大学教養部紀要. 第二部, 自然科学 11: 55-65(1977)}, pages = {55--65}, title = {界面活性剤による染料の変色に関する測色学的研究(第一報)}, volume = {11}, year = {1977} }
