Author(s): Chauhan Dhruv, Jay Bergi and Ratna Trivedi
Abstract: Heavy metal contamination in industrial wastewater presents serious environmental and health risks due to the persistence and toxicity of metals such as chromium, nickel, copper and manganese. This study investigates the use of reverse micelle-based extraction for the removal of these heavy metal ions from both synthetic and CETP wastewater. CTAB and SLS/SDS were employed to form reverse micelles for the selective extraction of metal ions. Parameters such as pH, contact time (15-45 min), surfactant concentration (10,20,30 mM) and sample volume (10-50 mL) were systematically varied. Results demonstrated significantly higher removal efficiencies in CETP wastewater, with optimal conditions around 10-15 mM surfactant concentration and 30 minutes contact time. Maximum efficiencies recorded were 99.41% for copper (SLS), 95.69% for manganese (SLS), 79.73% for nickel (SLS) and 61.84% for chromium (CTAB). The study further analyzed the feasibility of applying a 1:2 micelle solution to wastewater ratio. The finding confirm that reverse micelle extraction is an effective and scalable technique for industrial wastewater treatment, ensuring high removal efficiency while optimizing process conditions for large-scale applications. Future research should focus on refining surfactant concentration to enhance cost-effectiveness and sustainability in real-world operations.
