    • Abstract

       

      A high surface area-activated carbon from water treatment sludge (WTS) was employed as adsorbent material to remove methylene blue (MB) dye from aqueous solutions. In this research, the effect of parameters of adsorbent dosage, time of contact, and pH on adsorption capacity and efficiency were determined. Global desirability methodology was applied by using central composite rotational statistical design in order to optimize the adsorption of dye solution of MB by washed activated sludge carbon (WASC). Activated carbons obtained from WTS were characterized by FTIR, TGA, XRD and BET techniques. The mesoporous material WASC showed a total pore volume of 0.439 cm$^3$ g$^{-1}$ and the largest specific surface area of 582.0 m$^2$ g$^{-1}$. The production of WASC indicates to be an excellent option in thesustainable use of WTS residue.
