Abstract: Methods of making catalytically active metal-triazine treated carbon particles, and the resultant catalytically activated metal-triazine sorbent carbon media. The particles are formed by soaking an activated carbonaceous product in an oxidizing acid solution and exposing the oxidized activated carbon to at least one metal-triazine complex in solution for a time sufficient to form metal-triazine impregnated carbon particles. The impregnated carbon particles are heated in a non-oxidizing atmosphere to render calcined metal-triazine impregnated carbon particles, which are cooled to form catalytically active metal-triazine treated carbon particles that remove chloramines from aqueous solution. The resultant catalytically activated metal-triazine treated carbon particles are formed into filter media and/or blocks for removing at least chloramines from aqueous solution.
