Abstract
Active carbons were prepared from apricot stones and pecan shells either by chemical or physical methods. The activated carbons thus obtained were characterized by their textural properties using low temperature adsorption of nitrogen and by their surface chemistry using the base neutralization capacity measurements. The decolorizing uptake of methylene blue dye. Measuring the adsorption of phenol and alphanaphthol from their aqueous media followed the potentiality of the activated carbons for the removal of organic pollutants from water. The capacity of the activated carbons from the removal of heavy metals from water was determined by measuring the uptake of Cr(VI) from aqueous solution. The activated carbons prepared in this investigation exhibited high surface areas and large pore volumes. These carbons exhibited also higher adsorption capacities for organic and inorganic pollutants from water.
