The Date Stones (DS) is an agricultural by-product, which contributes to large quantities in Egypt. The present study consists of the preparation of activated carbon (AC) from Date stones (DS), activated chemically by H3PO4 and preparation nano-Particles Activated Carbon (NPAC) by ball milling techniques for the adsorption of organophosphorus malathion from aqueous solution. Physicochemical parameters for these materials were calculated through the surface area, elemental analysis, and texture porosity. The effects of environmental factors on capacity of adsorbents were conducts. The results reveal that used nano-particales activated carbon lead to minimize time and dose as well as increasing the adsorptive capacity. Nano-particales activated carbon was more effective than activated carbon in removal malathion pesticide from aqueous solution.
