Catalytic Wet Peroxide Oxidation of Naproxen Using Iron and Copper Containing Titanium- Pillared Bentonite
Naproxen is found in municipal sewage, surface waters, and drinking waters because it is one of the widely used non-steroidal, anti-inflammatory painkillers. Naproxen affects human health even at very low dosages and causes environmental pollution. Therefore, the elimination of toxic drug compounds like naproxen has been a significant environmental problem and the development of alternative refinement methods for these compounds has become prominent in recent years. In this study, elimination of naproxen from waters was investigated in the catalytic wet peroxide oxidation. Titanium-pillared bentonites (Ti-PB) including iron and copper were used as the catalyst. The catalytic performance studies revealed that the catalytic performance of the Titanium-pillared bentonite with iron (Fe/Ti-PB) was higher than that of both Ti-PB and Titanium-pillared bentonite with copper (Cu/Ti-PB). The catalytic performance studies also showed that catalytic performance changed depending on catalyst concentration, naproxen concentration, and H2O2/naproxen molar ratio.
