摘要：

The kinetics of photocatalytic degradation of 2-, 3- and 4-nitrophenol in aqueous dispersions containing TiO2 (anatase) has been investigated at different initial values of pH and concentrations of substrate. A pseudo-first order kinetics with respect to the nitrophenol concentration was found to hold; an increase of the substrate concentration and the initial pH was detrimental on the degradation rate.
