Textile industry wastewater is a significant source of pollution, often containing hazardous organic
dyes like Crystal Violet (CV). Photocatalytic degradation using semiconductor materials such as
titanium dioxide (TiO2) presents a promising solution for wastewater treatment due to its effectiveness
in breaking down organic pollutants under UV irradiation. This study investigates the efficiency of
TiO2 as a catalyst for the photodegradation of CV removed from textile wastewater. Experimental
trials were conducted in a batch reactor under UV irradiation, with CV (20 ppm) and varying
concentrations of TiO2 catalyst. Results revealed a significant reduction in CV concentration with
increasing catalyst dosage (to 0.1 g/L) and irradiation time. The optimal conditions for maximum
degradation efficiency were determined, highlighting the potential of TiO2 photocatalysis for textile
wastewater treatment. Furthermore, the kinetics of CV degradation were analyzed to understand the
react...ion mechanism and rate. The degradation of the dye (20 ppm) was 98% for 95 min with 0.1 mg/L
TiO2. This research contributes to developing sustainable and efficient methods for treating textile
wastewater, addressing environmental concerns associated with dye pollution.
