Pollutants such as dyes, detergents, agro wastes, inorganic substances, pesticides, and herbicides, etc. are the main reason for water pollution. Many toxic organic contaminants in wastewater have been degraded through photocatalysis. So, nowadays researchers have been working for the removal and degradation of organic pollutants using some metal iodides as a photocatalyst. Present work comprises the synthesis of Cadmium Bismuth Iodide photocatalyst and its precursors through simple precipitation method and solid-state reaction. Cadmium Bismuth Iodide characterizes through XRD, FESEM, EDX UV-Vis analysis. Comparative photocatalytic degradation of Azure-A and Toluidine blue was studied using an as-prepared catalyst. The impact of several factors like pH, the concentration of Azure-A and Toluidine blue dyes, amount of Cadmium Bismuth Iodide and irradiation time were examined. Increment in the reaction rate of both dyes was monitored with the help of a spectrophotometer. A tentative mechanism has been proposed for photocatalytic decomposition of both dyes.
