Abstract

Until recently, synthetic organic dyes were considered micropollutants due to their low concentrations in the environment, but recent data indicate that dye pollution is becoming an increasing problem. The production process, determination of product quality parameters and environmental requirements require analytical control. The article describes new azo dyes based on carbo- and heterocyclic alpha-dicarbonyl compounds and presents the results of their determination by photometric method. Optimal absorption wavelengths of solutions of the compounds, specific absorption coefficients, detection limits and linear ranges of determination are established.
