Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 1,   Pages 65-72 doi: 10.1007/s11783-010-0010-y

Abstract: The limiting chlorine demand, which quantifies chlorine reactive natural organic matter (NOM) on an equivalentbasis, was mathematically defined by the relation between ultimate chlorine residue and initial chlorineIt was found experimentally that NOM in water has limiting chlorine demand that increases with chlorineThe results also demonstrated that the effect of chlorine dose on the rate of chlorine decay can be quantitativelyinterpreted with the limiting chlorine demand.
