Fenton's reagent minimum dosage for remediation of water contaminated with dyes
Keywords:azoic dyes, oxidation-reduction potential, Pelileo, textile industry
AbstractEffluents from the textile industry not only represent a latent threat to biodiversity on our planet but also to humans due to the pollution generated by industrial dyes. In this study a Fenton process was evaluated for the decoloration of water contaminated with yellow 160, blue 81 and red 190 with an initial concentration of 3300 mg.L-1 and a chemical oxygen demand of 1719 mg.L-1. Changes in pH and molar doses of ferrous sulfate and hydrogen peroxide were evaluated. The Fenton process allowed 99,9% removal of organic matter and 100% removal of turbidity when it worked at pH 3,5 and molar dose Fe+2/ H2O2 between 1:3 and 1:5. By spectrophotometric scanning and measurement of redox potential, it was shown that the quality of decontaminated water resembled the ultrapure water type I.
