토양에서 클로르피리포스의 동력학적 거동 = Kinetic behavior of chlorpyrifos in soil

다국어 초록 (Multilingual Abstract)

We have investigated physicochemical characteristics and behavior of chlorpyrifos(CPF) in the agricultural soil, soil + dry waste food(DWF) and soil +manure. Experiments were accomplished biological degradation of samples loaded with chlorpyrifos in incubator at 27℃ during 30days in laboratory. In this study, Sample containing soil + manure has shown to be better biological degradation than sample of soil + DWF. The kinetics of chlorpyrifos oxidation catalyzed by agricultural soil, soil + DWF, and soil + manure can be described by Henri-Michaelis-Menten equation, V=(Vmax)/( Km+ C), where Vmax is the maximum velocity and Km the concentration of the substrate(C) corresponding to an initial(V) half of Vmax. The value of Vmax and km is 0.0588㎍CPF/g.soil.hr and 7.3529㎍CPF/g.soil in agricultural soil, 0.0601㎍CPF/g.soil∙hr and 4.4117㎍CPF/g.soil in the soil loaded DWF and 0.0890㎍CPF/g.soil∙hr and 4.2818㎍CPF/g.soil in the soil added manure. Therefore the order of Vmax. were Manure> DWF> Agricultural soil.
