【Abstract】 The cationic surfactant metallomicelle made from CTAB micelle and crown Schiff base transitional metal complexes was used in catalytic hydrolysis of Bis(4-nitrophenyl)phosphate(BNPP)in this paper.The study on BNPP hydrolytic kinetics shows that the release rate of the second p-nitrophenol of BNPP is higher than that of the first p-nitrophenol of BNPP,and the catalytic activity of the metallomicelle is higher than that of the complex aqueous solution.Michanelis constant and the apparent active energy for the catalytic reaction were calculated.更多还原
