摘要：
The kinetics of interactions of cerium(IV) with nonionic surfactants viz. Titron x-100 (polyoxyethylene (10) octyl phenol) and Brij-35 (polyoxyethylene glycol dodecyl ether) have been studied spectrophotometrically in HClO4 medium in the temperature range of 35 to 55 degrees C. The reaction rate showed a first order dependence with respect to cerium(IV). The observed rate constant was found to be proportional to [surfactant] at lower concentration while at higher [surfactant] the rate was independent to surfactant. A spectrophotometric evidence for association/complexation of cerium(IV) with surfactant monomer has been obtained. A mechanism for the interaction has also been proposed.
