摘要

A new sensitive method for the determination of deltamethrine pesticide in ppm level is described.The method is based on the hydrolysis of deltamethrine to produce cyanide ion which reacts with bromine water to form cyanogen bromide.To this solution on adding potassium iodide solution to remove excess of bromine which react with Leuco Crystal Violet.The formation of dye has maximum absorbance 590 nm and Beer's law is obeyed in the range of 0.4-2.6 ppm.The molar absorptivity,Sandell's sensitivity,correlation coefficient have been determined.The method is highly reproducible and have been successfully applied to the determination of deltamethrine pesticides in environmental agricultural and biological samples.
