| Abstract: | The kinetics and the mechanism on PNPP hydrolysis catalyzed by the metallomicelles made up of the complex and the surfactant are investigated. A kinetic mathematical model of PNPP cleavage catalyzed by dinuclear copper(II) complex was proposed. The results showed: the PNPP catalytic hydrolysis was intramolecular reaction in the metallomicelles; the two copper(II) ions revealed the synergistic effects in the PNPP catalytic hydrolysis; the metallomicelle made of oxamido-bridged dinuclear copper(II) complex and the surfactant showed high activity in the PNPP catalytic hydrolysis. |
