Degradation of yellow-GCN by photolysis with UV-light and solar irradiation using C-N-codoped TiO2 catalyst

摘要

The degradation of textile dye (Yellow-GCN; C28H14N2O2S2) has been done by UV-light and solar irradiation photolysis using C-N-codoped TiO2 catalyst. Degradation of yellow-GCN by UV-Light photolysis is conducted using 10 watt UV lamp (λ365 nm). The intensity of solar during the degradation of yellow-GCN is 27300 lux. Both of photolysis method has been done without and with C-N-codoped catalyst on varied degradation times. 120 mg/L of yellow-GCN could be degraded by 5,40% after 120 minutes UV-light irradiation without catalyst, and the degradation percentage increase to 23,6% by using 10 mg C-N-codoped TiO2 catalyst. While yellow-GCN could be degraded18,7% after 120 minutes solar irradiation and the degradation percentage increase to 38,0% by using 10 mg C-N-codoped TiO2 catalyst.
