Abstract

A spectrophotometric method for the determination of 1,4-dihydroxyanthraquinone in a mixed solvent system consisting of sulfuric acid and N,N-dimethylformamide is described. The effect of sodium carbonate, anthraquinone and mechanical impurities (dust) on the results is discussed. The accuracy of the measurements is better than 1%.
