Treatment of real cosmetic effluent resulting from the manufacture of hair conditioners by reduction degradation, adsorption and the Fenton reaction

Abstract

The objective of this study was to investigate the pollutant matrix for the manufacture of hair conditioners, by combining the treatment systems through reductive degradation/adsorption with assisted Fenton reaction. The procedure involved using 0.20g of metallic iron in the form of steel wool (medium coarse), with effluent in pH 3.0 for reductive degradation/adsorption and for Fenton reaction was used Hydrogen peroxide was used in 220 mg L-¹, for a total period of 18 min. There was a rate of 84.55% for the chemical oxygen demand and 17.93% for turbidity. The techniques employed were useful since the composition is diverse, with a high organic and non-biodegradable load.
