SDS胶束对孔雀绿褪色反应的影响

研究了十二烷基硫酸钠（SDS）表而活性剂胶束和预胶束对孔雀绿褪色可逆反应的影响，建立了1－1型可逆反应的胶束催化模型和预胶束催化模型，获得了胶束相中正逆反应的速率常数和预胶束的平均聚集数．结果表明，SDS胶束和预胶束对正反应有禁阻作用，而对逆反应有催化作用．

Effect of SDS Micelles and Premicelles on the Alkaline Fading of Malachite Green

Effect of SDS micelles and premicelles on the alkaline fading reversible reaction ofmalachite green has been studied. Micellar and premicellar catalytic models for the 1-1 typereversible reaction have been proposed.The rate constants of forward and backward reactions and equilibrium constants of the alkalinefading reversible reaction of malachite greed in micellar phase have been obtained by the micellarmodel. Under premicellar condition the average number of SDS molecules per substrate moleculewith n detergent molecules have been obtained by the premicellar catalytic model.The results indicate that both SDS micelles and premicelles exhibit an inhibiting effect forthe forward reaction. While they exhibit an accelerating effect for the backward reaction ,Theseresults were reasonably accounted for with electrostatic interaction.
