- During the last two decades, the photocatalytic oxidative treatment of organic contaminants in various wastewaters has been numerously investigated as an emerging, environmentally friendly, costeffective method and attracted considerable attention due to increasingly restrictive environmental
In this study, we have investigated the photocatalytic oxidative hydrolysis and solubilization of
organic compounds in aqueous TiO2 (Degussa P25) and modified TiO2 (Au(0 ~ 1.2 wt%)-TiO2(P25)) suspensions in the presence of artificial UV light. The effect of process parameters such as initialorganic concentration (25 ~ 100%), photocatalyst loading (0.05 ~ 2 g/L), UV power intensity (0 ~
36W), solution pH (4 ~ 12) on the photocatalytic hydrolysis/solubilization has been assessed
Photocatalytic oxidative treatment resulted in the high degree of hydrolysis and solubilization of
particulate organics. The highest extent of an increment of soluble organic concentration at the end of operation time of 60 min was 110%. Tabu search, neighbor search based meta-heuristic, which utilizes the characteristic of solution space in order to search the most attractive values was used for calculating the optimal operating conditions. The simulated highest hydrolysis rate constant described by pseudo-first order rate constant was 3.2 h-1 under the optimal operating conditions.
