PHOTOCATALYTIC DEGRADATION OF ROSE BENGAL BY SEMICONDUCTING TIN SULPHIDESHWETA SHARMA, R. K. MALKANI, RAKSHIT AMETA AND SURESH C. AMETAAbstract Most of the textile, dyeing and printing industries are creating water pollution by discharging their effluents directly to the nearby water resources. Different methods are in use for removal of these effluents, but these methods are associated with some or other demerits. Photochemistry may play an important role in solving this problem. Semiconductors are used as photocatalysts for removal of dyes from their solutions. In the present investigation, semiconducting tin sulphide has been used as a photocatalyst for the removal of rose Bengal. Different parameters like pH, concentration of dye, amount of semiconductor and light intensity, which affect the rate of the reaction have been studied. A mechanism has also been proposed.
