臭氧氧化水中多菌灵的动力学研究

Ozonation knetics of aqueous carbendazim

在半序批反应器中,研究了O3氧化水中多菌灵的动力学,确定了相对于O3和水中多菌灵的臭氧化反应的反应级数。结果表明,O3氧化多菌灵为准2级反应,水中多菌灵的臭氧化反应速率方程为:k=1.11×exp(-48864/RT)(L.mol-1.s-1),表观反应活化能约为48.86 kJ.mol-1。

In a semi-batch reactor, the ozonation kinetics of aqueous carbendazim was explored. The reaction order relative to both dissolved ozone and carbendazim belonged to a first-order type. Thus, the ozonation of aqueous earbendazim followed a quasi-second order reaction. Furthermore, the reaction rate constant was given as k = 1.11×exp （-48864/RT） （L·mol^1·s^-1 ）, the apparent activation energy was about 48.86 kJ·mol^-1.
