Abstract

This paper evaluates the treatment of textile dyeing wastewater by using steel scrap as adsorbents and heterogeneous catalysts for Modified Fenton oxidation. The efficiency of the process was explored as a function of the experimental parameters: pH, hydrogen peroxide concentration and Steel scrap content. The composites with high steel scrap content were effective to adsorb colour and COD in textile wastewater, and the adsorptive capacity increased with the superficial iron concentration. These steel scrap was also used as heterogeneous Fenton catalyst and had the advantage of being effective at pH 3.0 with a consumption of H2O2 lower than required by the homogeneous Fenton process.
