Abstract

In this research, DECOLORIZATION and MINERALIZATION of Basic Blue 41 (BB 41) were investigated by nanophotocatalytic process using immobilized TITANIA NANOPARTICLES in a batch photoreactor. Photocatalytic DECOLORIZATION and MINERALIZATION processes of dye solutions were performed at PILOT SCALE (10 L). To obtain the details of the photocatalytic degradation of BB 41, UV-Vis and Ion Chromatography (IC) analyses were employed. The effects of major variables governing the efficiency of the process such as H2O2 dosage, dye concentration and anions (NO3-, Cl-, SO42-, HCO3- and CO32-) were investigated. Kinetic analysis indicates that the photocatalytic DECOLORIZATION rates can usually be approximated first-order model. The nitrate and sulfate anions were measured as photocatalytic MINERALIZATION products of BB 41. The results show that the employment of desired operational parameters may lead to complete DECOLORIZATION and MINERALIZATION of BB 41 at PILOT SCALE.
