摘要

乳酸的钒(V)氧化与乳酸、钒(V)、H+和HSO4呈一级依赖关系。在外部添加表面活性剂的情况下，这些观察结果保持不变。研究了阳离子表面活性剂(CPC)、阴离子表面活性剂(SDS)和中性表面活性剂(TX-100)的添加效果。CPC对反应有抑制作用，SDS和TX-100对反应有不同程度的促进作用。通过考虑表面活性剂与反应物之间的疏水和静电相互作用来解释所观察到的效应

Micellar Effects on Vanadium(V) Oxidation of Lactic Acid in Aqueous Acid Media: A Kinetic Study

Vanadium(V) oxidation of lactic acid shows first order dependency on lactic acid, vanadium(V), H+ and HSO4 . These observations remain unaltered in the presence of externally added surfactants. The effect of adding a cationic surfactant (CPC), anionic surfactant (SDS) and neutral surfactant (TX-100) has been studied. CPC inhibits the reactions while SDS and TX-100 accelerate the reaction to different extents. Observed effects have been explained by considering the hydrophobic and electrostatic interaction between the surfactants and reactants
