Abstract

Heterogeneous photocatalytic degradation of amaranth has been investigated in aqueous medium using visible light using N, S-doped TiO₂. The doped titania has been prepared by sol-gel method. The rate of photocatalytic degradation of dye was monitored spectrophotometrically. The effect of variation of different parameters like pH, concentration of amaranth, amount of photocatalyst, dopant percentage and light intensity on the rate of photocatalytic degradation was observed. A tentative mechanism for the photocatalytic degradation of amaranth has also been proposed.

Keywords: Amaranth, N, S-doped titania, Photocatalytic degradation.
