Abstract

Many toxic and non-biodegradable natural organic matters can pose environmental threats to human health and ecosystem. Nicotine is one of toxic organic compounds detected in river, industrial waste and domestic wastewater. Photolytic process is one of the efficient methods used to eliminate nicotine in wastewater in the presence of C-N-codoped TiO2 catalyst by using UV and visible light. Nicotine was degraded by UV light 10 watt (λ= 365 nm) and visible light (Philips LED 13 watt 1400 LUX), with and without addition of C-N-Codoped TiO2 catalyst. The result is measured by UV-Visible Spektrophotometer at λ 200-500 nm. Degradation of nicotine solution with concentration 0,2 mg/L and 0,025 mg/L for 4 hours in the presence of catalyst showed the amount of degradation about 15,405 and 80,43% respectively. However, percent degradation is much lower in the absance of catalyst 7,86% and 47,27% respectively. Keywords: C-N-Codoped TiO2, degradation, nicotine, photolysis
