Development of an instrumental method of determining the color intensity of textile wastewater

Summary

A new instrumental method of determining the color intensity of textile wastewater with the use of a scanning spectrophotometer that accounts for the specificity of human vision has been developed. This ensures the conformability with the traditional method of determining color intensity by dilution rate (the determinations do not differ much). However, to carry out the analysis collecting spectral data on the colored sample and processing it with the help of specially developed «Coloration-monitoring» software will be enough. The detailed procedure of the analysis is presented. Compared to the traditional method the developed method provides for reducing significantly the analysis time; no bright lighting or special cylinders made of flint glass is required; the consumption of distilled water is also reduced. The key advantage of the method is the complete elimination of judgmental factor in determining this parameter. The method is characterized by high reproducibility that will improve the validity of the color intensity determinations. The method of determining color intensity based on the absorbance spectrum parameters can be used by the enterprises that monitor the given indicator (water and wastewater services providers, committees for natural resources and environmental protection, industrial enterprises, environmental organizations etc.).
