Use of a New Nanosized Photo Catalyst BaO3TiO.SrO3TiO-An Eco-friendly Process for Removal of Coloring Agents
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2013, Vol 3, Issue 1
Abstract
Colouring agents are used widely and when not consumed are excreted in environment polluting it. Most common pollutants are dyes, synthetic or natural. These dyes were removed through photo catalytic degradation process using a new semiconductor BaO3TiO.SrO3TiO. The optimum conditions were extracted by varying pH, concentration of dye, amount of semiconductor, intensity of light etc. the process follows pseudo first order kinetics which was confirmed on kinetic parameters. Formation of nontoxic degraded products like NO2, CO2, H2O etc makes the process of immense importance. Participation of OH free radical was confirmed by use of scavenger.
