| 中文摘要 | Hydrolysis of triffoxystrobin was investigated in pH 4-10 aqueous solutions at 25, 40 and 50 degrees C. Its photochemical experiments in acidic, neutral, alkaline solutions and 1-10 mg/L humic acid solutions were conducted. Trifloxystrobin hydrolytic rate was first-order with respect to hydroxide ion concentration. For each 10 temperature rising, the rate constant for hydrolysis increased 2-4 times. The photolytic T-1/2 of trifloxystrobin at pH 4, 7 and 9 was 13.0, 11.9 and 4.3 h, respectively. In the 1-10 mg/L humic acid solutions, the photodegradation rate constants corrected for light screening of trifloxystrbin were 0.0592-0.0577 h(-1), basically decreasing with the humic acid concentration increasing. It was concluded that in the aqueous solution, the key nucleophilic reaction partner was hydroxyl ions. Raise of temperature could accerlate hydrolysis of trifloxystrobin. The hydrolysis could accelerate the photolysis of trifloxystrobin and light screening had an effect on the photodegradation rate constants of trifloxystrobin. |
