  • Patent number: 9095840
    Abstract: An activated carbon material for removing a contaminant from a liquid. The activated carbon material can be a plurality carbon grains that have a pore volume of approximately 0.1 milliliters per gram (mL/g) in the range of less than about 15 angstroms in width. The carbon grains can also have or contain a nitrogen-containing species having a concentration of more than 2 atomic percent nitrogen. A plurality of the carbon grains can be used to make a contactor that is operable to remove or reduce perchlorate having a concentration of 20 parts per billion (ppb) to less than 4 ppb from 4,500 bed volumes of water with the nitrogen-containing species leaching off of the carbon grains less than 0.1 mg/L. The activated carbon material can also be electrochemically regenerated.

  • Publication number: 20050167366
    Abstract: 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.
