Studies on N-o-hydroxybenzylglycine and its complexes(Ⅷ)──Mechanism and kinetics of redox reaction between cobalt(Ⅱ)complex and hydrogen peroxide
【摘要】 用分光光度法研究了Co(Ⅱ)-HBG络合物与H2O2的氧化还原反应动力学及反应机理,求得动力学参数及第一步反应的热力学常数ΔH≠、ΔS≠.作者认为,此氧化还原反应不可能按内层电子转移的机理进行,而是经过外层电子转移机理进行的.
【Abstract】 Mechanism and kinetics of redox reaction between cobalt(Ⅱ) complex of N-o- hydroxybenzylglycine(HBG) and H2O2 have been investigated spectrophotometrically. The kinetic parameter and the thermodymic quantities, ΔH≠ and ΔS,of the first reaction have been obtained.Autors propose that the electron transfer prefer to occur through outer sphere mechanism.
