摘要：The kinetics of monochlorodimedone (MCD) chlorination with sodium hypochlorite (NaOCl), chloroisocyanurates (2Cl-and 3Cl-ICA), N-chlorosuccinimide (Cl-succinimide), and chloramine T and B were studied. The chlorination of MCD was recognized by a decrease in absorbance at 290 nm and at pH 7. Instantaneous chlorinations occurred with NaOCl and chloroisocyanurates. The rate constants for the chlorination with Cl-succinimide and chloramine T and B were determined. The reactions were determined to be second order-first order in each reactant, and were dependent on temperature. The observed second order rate constants at 15°C for Cl-succinimide, and at 25°C for chloramine T and B were 1500, 61.8 and 41.5 M-1·S-1, respectively.
