Use of Coprecipitated ZnS-MnS in Degradation of Rose BengalAuthor(s): Neelima Rajawat, Yuvraj Jhala, Rakshit Ameta and Suresh C. Ameta
The photocatalytic degradation of rose bengal has been investigated in presence of coprecipitated ZnS-MnS. The rate of photocatalytic degradation of dye was observed spectrophotometrically. The effect of variation of different parameters like pH, concentration of dye, amount of semiconductor and light intensity on the rate of photobleaching was also observed. A tentative mechanism for the photocatalytic degradation of rose bengal has also been proposed.
