摘　　要：The hydrolysis of bis(4-nitrophenyl)phosphate(BNPP)catalyzed by cyclotetraenetetraamine-Ce(Ⅲ)complex was studied in this paper at 30℃ and pH7.2.The experimental results indicated that cyclotetraenetetraamine-Ce(Ⅲ)complex dramatically accelerated the hydrolysis of BNPP.The catatalytic mechanism was proposed in this paper and the kinetic mathematical model of the catalytic reaction was also developed according to the mechanism.The mixed system of cyclotetraenetetraamine-Ce(Ⅲ)complex and CTAB micelles inhibited the hydrolysis of BNPP,while the mixed system of cyclotetraenetetraamine-Ce(Ⅲ)complex and Brij35 micelles accelerated it.The hydrolysis of bis(4-nitrophenyl)phosphate(BNPP)catalyzed by cyclotetraenetetraamine-Ce(Ⅲ)complex was studied in this paper at 30℃ and pH7.2.The experimental results indicated that cyclotetraenetetraamine-Ce(Ⅲ)complex dramatically accelerated the hydrolysis of BNPP.The catatalytic mechanism was proposed in this paper and the kinetic mathematical model of the catalytic reaction was also developed according to the mechanism.The mixed system of cyclotetraenetetraamine-Ce(Ⅲ)complex and CTAB micelles inhibited the hydrolysis of BNPP,while the mixed system of cyclotetraenetetraamine-Ce(Ⅲ)complex and Brij35 micelles accelerated it.
