Photocatalytic degradation of p-nitrophenol in water with AgCl catalysis
Chemical Journal on Internet(2006)
摘要
AgCl colloid was obtained by using AgNO3 reacted with NaCl in aqueous solution and then sensitized with UV light illumination. The photocatalytic degradation of p-nitrophenol in aqueous was realized by near UV light or sun light illumination with AgCl catalysis. The degradation kinetics of p-nitrophenol was found to be first-order and the degradation rate coefficient is -0.0337. The degradation rate of p-nitrophenol was increase with increasing of AgCl concentration and decreased with increasing of the initial concentration of p-nitrophenol. It was also found that AgCl was stable during the experiments and can be reused.
