Photodegradation of o-cresol by ZnO under UV irradiation
نویسنده
چکیده
The effective removal of o-cresol is currently both an environmental problem. This paper shows how degradation of o-cresol was carried out, in the presence of UV; by ZnO as photocatalyst. To measure the efficiency of photodegradation, the different variables studied included amount of photocatalyst, concentration of o-cresol and pH. The results showed photodegradation was favorable in the pH 6-9 range with amount of photocatalyst 2.5g/L, and o-cresol concentration 100ppm. The detected intermediates were 2-methylresorcinol, 2.5-hydroxybenzaldehyde and salicylaldehyde. TOC studies show that 94% of total organic carbon is removed from solution during irradiation time. This study indicates the great potential of ZnO to remove aqueous o-cresol under UV irradiation.

Enhanced photodegradation of o-cresol in aqueous Mn(1%)-doped ZnO suspensions.
The effective removal of o-cresol is currently both an environmental and economic challenge. ZnO is not only an efficient photocatalyst but is also cost effective, as its photoabsorption can extend from the ultraviolet (UV) to the visible range thereby allowing the use of inexpensive visible light sources, such as sunlight. The principal objective of the present work is to investigate the visib...
