Abstract

The standard method to determine industrial effluents color is multiple dilution method which has defects of reproducibility, obscure endpoint of dilution, and subjective influence. For this, based on the theory of complementary color, an integral spectrophotometry method was proposed to determine the color of industrial effluents. The results from vary hues show that there is a good linear relationship between the spectral curve area S and the color C in the selected wavelength range, and all the correlation coefficient R2 are more than 0.99. The method validation by pharmaceutical wastewater shows that the method is feasible and its results are consistent with that of the dilution method. All the relative error are less than 5%, and the method have merits of sound stability and reproducibility. So, it can be widely used as a substitute for multiple dilution method to determine the color of industrial wastewaters.
