A method of removing chlorine, chloramine, or both chlorine and chloramine from a fluid, the method comprising:

• providing a sorbent material, the sorbent material being formed from a carbonaceous material comprising coconut that is activated to form a precursor activated carbon, the sorbent material comprising at least about 1.3 wt. % nitrogen as measured on a dry precursor activated carbon basis;
• at least about 1,000 mg/kg of iron as measured on a dry precursor activated carbon basis;
• and wherein the sorbent material has a volumetric chloramine removal amount of about 85 mg/mL or more when measured with a stream of water that contacts the sorbent material, and contacting the sorbent material with a fluid.
