چکیده انگلیسی
Absorption spectrum of imidacloprid was measured using spectrophotometer and the most intensive characteristic peak (269Â nm) was found. The function relationship between imidacloprid concentration and absorbance was obtained with a good linear relationship(R >Â 0.99). The hardware platform for pesticide degradation was designed and built based on ultraviolet light technology, and imidacloprid degradation experiments were conducted based on the platform. It was proposed to describe degradation effect using absorbance change, and prediction model of pesticide residues degradation was obtained according to the relationship between degradation time and absorbance. The results showed that it was feasible to characterize ultraviolet degradation effect according to absorbance change, degradation rate was 4.71% after ultraviolet irradiation for 1Â minute, and it was 98.43% after 10Â minutes.
