TiO2-Powdered Activated Carbon (TiO2/PAC) for Removal and Photocatalytic Properties of 2-Methylisoborneol (2-MIB) in Water

2-methylisoborneol (2-MIB) is a common taste and odor compound caused by off-flavor secondary metabolites, which represents one of the greatest challenges for drinking water utilities worldwide. A TiO2-coated activated carbon (TiO2/PAC) has been synthesized using sol-gel method. new TiO2/PAC photocatalyst successfully employed in photodegradation 2-MIB under UV light irradiation. In addition, combined results XRD, SEM-EDX, FTIR UV-Vis suggested that nano-TiO2 had loaded on surface PAC. Experimental removal indicated adsorption capacities PAC were higher than TiO2/PAC. However, natural organic matter (NOM) bearing water, efficiency 97.8% 65.4%, respectively, Moreover, it was shown presence NOMs distinct effect MIB simplified equivalent background (SEBC) model could not only be used to describe competitive NOM, but also represent photocatalytic process. comparison other related studies, there are few novel composite photocatalysts efficiently rapidly remove combination photocatalysis.
