ature and time and K 2 CO 3 /elutrilithe ratio on the surface area, porosity, and ash content of the adsorbents was studied. Various The black elutrilithe was from Shanxi province, China. It prior and post treatments have been tried to improve the quality contained 29.1% C, 36.0% SiO 2 , 18.2% Al 2 O 3 , and 16.7% of the adsorbents. An ideal active carbon adsorbent with a BET

Ca, Mg, Fe, Mn, Cr, Ni, Ti, and Na oxides. The BET surface surface area of 1236 m 2 /g and a total pore volume of 0.679 cm 3 / g has been obtained. The adsorbent is hydrophobic in nature and area of the original elutrilithe was 5.7 m 2 /g. exhibits large adsorption capacities for various phenolic com-Elutrilithe with a particle size smaller than 100 mesh, 3 pounds from aqueous solutions.
