Abstract
This method for determining microgram quantities of dieldrin is based on the color complex formed between dieldrin and diphenylamine in the presence of zinc chloride. The absorption at 650 micrometers by color reaction products in an acetic acid solution follows Beer's law. The method is general for most chlorinated insecticides, but specificity is gained through alkaline hydrolysis and chromatography.
