The treatment of highly alkaline and toxic industrial organic raffinate (IOR) containing pyridine its derivatives was studied by coupling catalytic wet air oxidation (CWAO) a biological process. CWAO IOR performed using 1 wt % platinum catalyst to degrade compounds present in the biodegradable intermediates. prepared characterized scanning electron microscopy, energy-dispersive X-ray spectroscopy, diffraction analysis. High-pressure liquid chromatography CWAO-treated effluent showed complete degradation pyridine. toxicity checked, it found be nontoxic. post-treated method, final within discharge limits prescribed statutory authorities. reusability studied, effective for four cycles. study suggests an solution addressing pollutants wastewater.
