| Summary: | 碩士 === 大葉大學 === 環境工程學系碩士班 === 100 === In this study activated carbon was product as an adsorbent by activating waste
sludge with diflerent chemical agents. 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.
