Abstract

Butyl acetate is an organic compound widely used in industry, focu- sing on industrial paint waste ef uents. Exposure to this pollutant at an average of 925 ppm can cause dizziness, drowsiness, respiratory tract irritation, and central nervous system suppression. That is why it seeks to minimize the risk associated with this contaminant through treatment alternatives. The characterization of the sample yielded the detection of the following contaminants: methyl ester, 1-butanol, 1-4 dioxane, butyl ester, 1-chlorobutane. The objective of this work was the design and development of combined treatments for the removal of butyl acetate in industrial waste ef uents. For this, a physicoche- mical treatment coupled to an advanced oxidation process (PAO) was implemented. The results showed that the coupled treatments are ef - cient for the removal of butyl acetate, methyl ester, 1-chlorobutane and 1-butanol, while for 1-4 dioxane it was reduced by approximate- ly 83%. The study was complemented with the evaluation of the fo- llowing parameters, resulting in a decrease in electrical conductivity of 99.5%, total suspended solids of 74%, color of 93%, turbidity of 55% and COD of 73%.
