Electroplating effluents are a significant source of toxic heavy metals, with hexavalent chromium being of particular concern due to its severe health hazards. This research investigates the efficiency of a Resin-Immobilized Photocatalyst (RIP-TiO₂) in removing Cr⁶⁺ from wastewater using a fixed-bed photocatalytic reactor. Experiments were carried out with both actual electroplating wastewater and synthetic wastewater, employing three RIP-TiO₂ dosages (30, 40, and 50 g) and sampling intervals of 0, 5, 15, 30, 45, 60, 75, 120, and 180 minutes. The reactor was operated with three column beds under UV-C irradiation (15 W). The study used two different types of media, electroplating wastewater (real wastewater) and synthetic wastewater (Cr6+ solution). The comparison initial Cr6+ concentrations measured were 1004.7 mg/L for real wastewater and 84.97 mg/L for synthetic wastewater. After 180 minutes of treatment with 50 g of RIP-TiO₂, removal efficiencies reached 70.67% for real wastewater and 37.64% for synthetic wastewater respectively. Datas were statistically evaluated using One-Way ANOVA followed by Tukey’s test. The findings demonstrate that resin-supported TiO₂ effectively reduces Cr⁶⁺ levels, with optimal performance obtained under acidic pH and prolonged contact time.
