Activated carbon from grape seeds upon chemical activation with phosphoric acid: Application to the adsorption of diuron from water

The preparation of activated carbon from grape seeds was studied by chemical activation with phosphoric acid. Grape seeds were pretreated with sulfuric acid to improve wettability and impregnated at different grape seed to phosphoric acid ratios (1:1-1:4). The impregnated grape seeds were carbonized...
