PHOTOCATALYTIC DEGRADATION OF INDIGO CARAMINE FROM AQUEOUS SOLUTION BY TIO2 NANOPARTICLE UNDER UV IRRADIATION

Abstract

Despite rising demand for chemical industry products and associated factories, the issues of environmental pollution have not improved, and the situation is rapidly deteriorating. The importance of dyeing companies in polluting the environment is evident in this regard. The photodegradation of Indigo caramine (IC) by Titanium dioxide (TiO₂) was studied using UV-absorption spectroscopy in this study. By adjusting the dye concentration, catalyst dose, pH, temperature, and H₂O₂ concentration, It was able to be determined the percentage of degradation of these nanoparticles on Indigo caramine. The Langmiur-Hinshelwood mechanism was used in this experiment. The percentage of degradation was exceptionally efficient at 4×10^-5 M dye concentration with pH 2.5 and constant catalyst concentration for nanoparticle. This demonstrates that Titanium dioxide (TiO₂) nanoparticles may remove Indigo caramine (IC) from waste water. The outcomes of this investigation resulted in a ground-breaking, cost-effective water pollution remediation method.
