Özet:

 

The kinetics of oxidation of ethylenediaminetetraacetic   acid (EDTA) by N-bromosuccinimide (NBS) in aqueous alkaline media was   investigated at 25°C. Analysis of the results showed the   reaction is first -- order with respect to [NBS] and apparently less than unit   order each with respect to [EDTA] and [alkali]. The influence of the   reaction products, ionic strength, temperature effect and dielectric   constant of the medium on the rate of reaction was studied. The   proposed mechanism is consistent with the observed kinetics. The reaction   constants involved in the mechanism were derived. There is a good   agreement   between the observed and calculated rate constants under different   experimental conditions.
