| 摘要 |
A composition as adsorbent and catalyst is manufactured by adding activated carbon into a aqueous solution comprising a plurality of metal salts, adjusting the solution to a predetermined pH value according to the types of the plurality of metal salts, drying the solution while slowly stirring at the same time, and calcining a product from the dried aqueous solution so as to obtain the composite as adsorbent and catalyst. The said composite can be used in a wastewater treatment method. The wastewater treating method comprises the steps of adding the said composite to wastewater comprising a contaminant, such that the contaminant is adsorbed onto the composite; and adding an oxidant to the wastewater. The oxidant is catalyzed by the composite to generate free radicals, which oxidizes the contaminant adsorbed onto the composite to thereby remove the contaminant from the wastewater.
