Characterization of activated carbon prepared from lignocellulosic natural residue:-Example of date stones-

The objective of this study is the characterization of activated carbon prepared from a lignocellulosic natural residue which is a vegetation waste “stones of dates” of the south of Algeria. After the preparation of the raw material for production, three types of carbon are pointed: a carbonized carbon at 600 ∘C, the two others are chemically pre-treated the first one pre-treated with the nitric acid (10%) and the second with the phosphoric acid (1/1) before their carbonization at 600 ∘C. Various results of characterization (rate humidity and ashes, specific surface, porous volume etc.) showed that the obtained carbons are comparable with those industrially prepared and could then be tested for example in the process of water treatment.
