PHOTOCATALYTIC DEGRADATION OF BISPHENOL E WITH NANO-SCLAED TiO2 IN AQUEOUS SOLUTION UNDER SOLAR RADIATION

Abstract

In this work focus was paid to the photocatalytic degradation of Bisphenol E with nano-scaled TiO2 solution under sunlight. Instruments used for characterization and study the removal efficiency were; visible ultraviolet spectrophotometer, SEM (acceleration voltage 25kV) and TEM (acceleration voltage 80kV), X-ray diffraction and BET surface area. Under the optimum conditions; (pH;6, Radiation time; 90 min, Catalyst wt; 0.2g, reaction temperature; 20 oC), complete degradation was obtained. Byproducts from this study could be similar to our previous ones since Bisphenol A and Bisphenol E have very similar structures, hence their decomposition intermediates most probable not to be far. it was found that the decomposition reaction of bisphenol E follows the pseudo-first-order reaction kinetics
