  • Abstract

    In recent years, heterogeneous photocatalysis has gained wide attention in water purification as one of the important advanced oxidation processes (AOPs) due to its effectiveness in degrading and mineralizing the organic compounds. N, S-codoped TiO2 has been prepared by sol-gel method with thiourea as dopant source. The rate of photocatalytic degradation of dye was monitored spectrophotometrically. The effect of variation of different parameters like pH, concentration trypan blue, amount of photocatalyst, dopant percentage and light intensity on the rate of photocatalytic degradation of dye was observed. A tentative mechanism for the photocatalytic degradation of trypan blue has also been proposed.
