Abstract
The rate of Trihalomethanes (THM) formation was experimentally observed to be first-order with respect to chlorine, and first-order with respect to humic acid precursors, and the overall reaction order was second-order. THM formation rate expression was formulated as a function of the concentration of THM Formation Potential (THMFP), residual chlorine concentration, reaction time and reaction temperature. A model is developed to estimate THM in water distribution systems. Since the calculated results are close to the measured values in the distribution system, it is suggested that this model is applicable to actual water distribution systems.
期刊介绍：
Chemosphere, being an international multidisciplinary journal, is dedicated to publishing original communications and review articles on chemicals in the environment. The scope covers a wide range of topics, including the identification, quantification, behavior, fate, toxicology, treatment, and remediation of chemicals in the bio-, hydro-, litho-, and atmosphere, ensuring the broad dissemination of research in this field.
