|a Chloramination has been widely applied for drinking water disinfection, with monochloramine (NH2Cl) the dominant chloramine species. However, under neutral pH, NH2Cl can autodecompose and react with chemical components in drinking water, thus decreasing disinfection efficiency. In tap water, the NH2Cl loss rate can be influenced by temperature, pH, Cl/N molar ratio, the initial NH2Cl concentration, and the natural organic matter (NOM) concentration. A good prediction of NH2Cl loss can assist in the operation of drinking water treatment plants. In this research, a kinetic rate constant <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="01999-ilm01.gif"/>)and a reactive site fraction (S = 0.43 ± 0.06) for the reaction between free chlorine released from NH2Cl autodecoposition and tap water NOM were derived from a kinetic model to predict the NH2Cl loss under various conditions. A temperature-dependent model was also developed. The model predictions match well with the experimental results, which demonstrates the validity of the model and provides a convenient and accurate method for NH2Cl loss calculations
