| Abstract: | The kinetics of degradation reaction of 2-chlororthyl ethyl sulfude(2-CEES)in sodium percarbonate/sodium molybdate system and single sodium percarbonate were studied at different temperatures,and the corresponding reaction rate was calculated.The reaction mechanism was proposed based on the analysis of the degradation products by LC-MS and reactive species by ESR.The results show that both systems are first-order reactions.The activation energy of sodium percarbonate/sodium molybdate on 2-CEES degradation i... |
