Abstract

Direct red-23 and Direct violet are non-biodegradable compounds containing azo component and carcinogenic. Direct red-23 and Direct violet had been degraded by ozonolysis, photolysis with UV lamp and solar irradiation methods using N-doped TiO2 catalyst. UV/Vis Spectrophotometer at wavelength 300-800 nm was used to measure the absorption of sample solution. The optimum weight of N-doped TiO2 catalyst was 20 mg. From the three methods obtained that ozonolysis method was the faster degradation process than photolysis with UV and solar irradiation. Direct red-23 and Direct violet was degraded as much as 55 and 50% within 20 minutes by ozonolysis.ABSTRAKZat warna Direct red-23 dan Direct violet merupakan senyawa non-biodegradable yang mengandung senyawa azo dan bersifat karsinogen. Direct red-23 dan Direct violet didegradasi menggunakan metode ozonolisis, fotolisis dengan sinar UV dan dengan penyinaran matahari, tanpa dan dengan katalis N-doped TiO2. Hasil penelitian diukur dengan spektrofotometer UV-Vis pada panjang gelombang 300-800 nm. Berat optimum katalis N-doped TiO2 didapatkan 20 mg. Dari ketiga metode didapatkan bahwa proses degradasi pada metode ozonolisis paling cepat dibandingkan dengan fotolisis sinar UV dan cahaya matahari. Direct red-23 dan Direct violet dapat didegradasi sebanyak 55 dan 50% dalam waktu 20 menit.
