| Abstract: | The paper systematically studies the influence of the dosage of enzyme,the concentration and dosage of activator Co2+,the absorbed wavelength,the time and temperature of reaction on enzymatic reaction and the influence of the dosage of Fast Blue B Salt and the time of color development on the system of color development.The result shows that adding Co2+ to the plant esterase to detect the pesticide residues in vegetables and fruits can increase the sensitivity of detection and cut down the lowest detection ... |
