Abstrakt

This study examined the effect of solution temperature on the photocatalytic degradation of methylene blue solution in water treatment photoreactor. The photoreactor made of TiO2 immobilized fluoropolymer beads which has the same refractive index of water. The photo reaction of the reactor in water purification was investigated by means of a recirculation experiment using an aqueous solution of methylene blue with a pseudo-first order kinetics. The result showed a pseudo-first order rate constant of reactor increased with rising the temperature. It was 1.3 times higher as changing the solution temperature from 293 K to 313 K. The temperature effect of reactor was estimated by Arrhenius equation. The estimated activation energy of this our reactor was 11.2 kJ/mol.
