Abstract

The rate–surfactant concentration profiles for the reaction of the insecticide paraoxon with hydroxamate ions (R (CO)· NHO−, R= CH3, R= C6H5, R= 2-HOC6H4) in aqueous solutions of cetyltrimethylammonium salts, CTAX (X−= Br−, Cl−, SO3H−) have been measured at pH11. 0 at 30° C. All these profiles are typical of micelle-assisted bimolecular reactions involving interfacial ion exchanges. The salicylhydroxymic acid–CTACl combination is ...
