[Modeling of inactivation kinetics of E. coli with free chlorine and monochloramine].
The inactivation of Escherichia coli with free chlorine and monochloramine was studied using bench-scale experiments in 0.03 mol/L phosphate buffered saline with pH 7.0 and at 20 degrees C. Inactivation data were fitted to Chick's law, Chick-Watson, Hom, Rational, Hom-Power law, Selleck model. A three-parameter Rational model incorporating a first-order disappearance term for free chlorine residual was found to best describe the observed inactivation of E. coli, and for monochloramine the two-parameter Selleck model was the best fit model.
