چکیده

Optimization of electric energy consumption in degradation of Indigo Carmine based on a new cylindrical batch suspension photocatalytic reactor designing concerning the main engineering parameters such as mixing, reaction kinetic, mass transfer, catalyst illumination, and inherent potential of contaminant was done. The most degradation efficiency was observed within in air flow rate 1.2L. min-1, initial hydrogen peroxide concentration 0.0294mol.L-1, pH between 2-3, initial dye concentration 10mg.L-1, and initial TiO2 dose 2g.L -1. Applying optimum condition eventuated 76.09% TOC reduction after 60 min reaction time. The results show that designed reactor is extremely affective in reduction of operational cost. keywords: Advanced oxidation processes, Acid Blue 74, TiO2 nanoparticles, photochemical reactor.
