Infrared Determination of Dithianon
Abstract An infrared spectrophotometric method of analysis of dithianon in concentrates and formulated powders containing zineb and sulfur has been developed. Dithianon is extracted with chloroform from the concentrate or formulation; the extract is evaporated and diluted to a specific volume with chloroform; and the dithianon present is determined from the infrared absorption at 1275 cm-1. From 20 to 80 mg dithianon in 10 ml chloroform are readily determined.
