A carbonaceous material that has been loaded with at least one ionic organic species or hydroxide species and at least one metal or alkaline earth metal. The ionic organic species or hydroxide species is at least one selected from the group consisting of: fatty acids, surfactants, organic carboxyl species, organic sulfonate species, organic hydroxyl species, organic phenolic species, organic lactone species, organic amine species, or hydroxide species.

Method for oxyanion removal from ground water

An activated carbon that is capable of adsorbing taste-and-odor-causing and other organic compounds, wherein the activated carbon comprises a uniquely modified carbonaceous material. The activated carbon comprising: (a) a pore volume per gram of the activated carbon more than about 0.32 mL in the pore width range between about 4 to 63 angstroms; and (b) a pore volume per gram of the activated carbon more than about 0.21 mL in the pore width range between about 63 to 500 angstroms; provided that the pore volume per gram of the activated carbon in the pore width range of about 20 to 63 angstroms is at least about 25% of the total pore volume per gram of the activated carbon in the pore width range of 4 to 63 angstroms, as measured per the Argon Adsorption Density Functional Theory protocol; provided that the activated carbon has a pH equal to or greater than 9.9, when immersed as a slurry in nitrogen-purged deionized distilled water, while the slurry contains about 10% by weight of activated carbon, as measured per the Slurry pH protocol.

Method of heat treating carbonaceous material to enhance its adsorption of taste-and-odor-causing and other organic compounds from water

A method for removing perchlorate or other anionic contaminates from ground water which comprises the step of passing the ground water over activated carbon, wherein the activated carbon has been either preloaded with an organic cation functional group or organic cation polymer or cationic monomer, or tailored with ammonium or other reduced nitrogen-containing compound.
