| 摘 要： | The effect of pressure on the hydrolysis rates and the degradation kinetics of environmentally persistent omethoate pesticide was studied. The results showed that the values of kobs increased and the values of activation volume (AV) decreased with increasing pressure. Among pH conditions (3.58, 6.01 and 8.5), pH 8.5 was found to be the unstable condition and its half-life was reduced from 263 min at 1 atm to 19.37 min at 10 atm. These results describe that high-pressure hydrolysis is a useful technique for the conversion of toxic organic phosphorus into inorganic phosphorus.

| Abstract: | The effect of pressure on the hydrolysis rates and the degradation kinetics of environmentally persistent omethoate pesticide
was studied. The results showed that the values of k
obs increased and the values of activation volume (AV) decreased with increasing pressure. Among pH conditions (3.58, 6.01 and
8.5), pH 8. 5 was found to be the unstable condition and its half-life was reduced from 263 min at 1 atm to 19.37 min at 10
atm. These results describe that high-pressure hydrolysis is a useful technique for the conversion of toxic organic phosphorus
into inorganic phosphorus. |
