摘要
Abstract
[ Objective] The effect of the initial concentration of carbenclazim, the adding amount of ozone and temperature on the apparent rate constant in the degradation of carbendazim was researched. [ Method ] The relationship between the apparent rate constant and reaction dose in the process of the carbendazim degradation in water was experimented. [ Results] The results indicated that under the condition of different doses of ozone-adding and initial concentrations the process of carbendazim degradation was matched with the pseudo-first-order kinetic model. The apparent rate constants had the positive relativity with applied ozone dose and negative correlation with initial concentration. The apparent rate constant was decreased with increment of initial concentration. However, the absolute removal rate of the reactants was increased, which indicated that the increment of initial concentration would be beneficial to the improvement of the utilization rate of ozone. The apparent rate constant was increased with the increment of temperature, which was consistent with the general law of chemical reaction. [ Conclusion] The reference for the safety and efficiency degradation of carbendazim was provided through the experiment.关键词
