This activated carbon was used as acarrier for titanium dioxide catalysts impregnated with elements of N,Cu and Ag.Four types of titanium dioxide catalysts N/TiO2 /AC(ZnCl2、ZnCl2+H3PO4、KOH)、 Cu/TiO2 /AC(ZnCl2、ZnCl2+H3PO4、KOH)、Ag/ TiO2 /AC(ZnCl2、ZnCl2+H3PO4、KOH)were used to degrade Malachite Green (MG) Methylene Blue (MB) Acid Red 27 (AR27).Optimal degradation conditions were discussed. Characterization of these catalysts was made by using ICP-AES,SEM/EDX andXRD.The experimental result demonstrated that elements Ag.Cu and N were doped onto TiO2/AC.The crystul type of titanium dioxide catalysl was shown to be anatase.The degradations of MG.MB and AR27 were described by first-order reaction model.It shown that MG.MB and AR27 could be degraded by these catalysts with light in visible region.Highest degradation rate was obtained with N-doped catalyst.Activated carbon as adsorbent produced by activating agent ZnCl2 showed better degradation and adsorption performance.
