The degradation of orange F3R textile dye (C.I.V at Orange 16; C29H12ClNO5) has been done by UV-light, visible-light and solar-light irradiation photolysis using C-N-codoped TiO2 catalyst. Orange F3R dyes are synthetic organic dyes which difficult degraded spontaneously in the environment. The heavy use of these dyes by industry will give negative impact to aquatic life. Degradation of orange F3R by UV-light photolysis is conducted using 10 watt UV lamp (λ=365 nm). Whereas, the intensity of visible LED light, Phillips 13 W is 2000 lux and solar-light during the degradation of orange F3R is 45.000 lux. All of photolysis method has been done without and with the addition of C-N-codoped catalyst on varied degradation times. Orange F3R dyes could be degraded by 11.82% after 180 min UV-light irradiation without catalyst, and the degradation percentage increase to 39.05% by the addition of 12 mg C-N-codoped TiO2 catalyst. The irradiation of visible light for 180 min can degrade the orange F3R dyes by 11.83% without catalyst and increase after addition 9 mg C-N-codoped TiO2 catalyst to 40.86%. While degradation percentage of solar irradiation photolysis is 22.81% without catalyst and increase to 64.12% by the addition of 6 mg C-N-codoped TiO2 catalyst.
