Photocatalytic Decolorization of Textile Effluent by using Synthesized Nano particles


The textile industry consumes considerable amounts of water during the dyeing and finishing operations. Dyes extensively used are found to be toxic and considered to be resistant to biodegradation. In this work, a detailed investigation was done on photocatalytic degradation for selected textile effluent. The two different nano particles, CaAl2O4-I was synthesized by using fuel urea and CaAl2O4-II by acetamide by solution combustion method. These nano particles were characterized by using X-ray diffraction (XRD), Scanning Electron Micrograph (SEM) and UV absorbance spectroscopy. The average size was found to be 39 nm for CaAl2O4-I and 42 nm for CaAl2O4-II. The band gap of the nano particle CaAl2O4-I was found to be 2.8 eV and CaAl2O4-II was 2.7 eV. These nano particles were tested for the photocatalytic degradation by varying parameters such as catalyst concentration, pH and dye concentration. Also, the efficiency of the synthesized nano particles were compared with the procured TiO2 of size < 25 nm.
