摘要：

The alkaline hydrolysis of methyl violet (MV) was studied by spectrophotometric method under pseudo-first-order conditions at 298 K. Cationic surfactant cetyltrimethylammonium bromide (CTAB) catalyzed the reaction. Addition of nonionic surfactant Triton X-100 (TX-100) exhibited significant influence on the CTAB catalyzed reaction by lowering the extent of catalysis. The kinetic data were analyzed by Piszkiewicz model of positive cooperativity. Linear Hill-type plots were generated with indices of cooperativity values greater than unity. The effect of counterions on the reaction rates was also studied in the presence of cationic surfactant (CTAB) and cationic-nonionic mixed surfactants (CTAB/TX-100).
