[Detection of furadan in biological fluids]

Optimal conditions have been determined for furadan isolation from biological fluids by means of the mixture of solvents ethyl acetate-acetone in volume 1:1. Possible purification of the compound from coextractive substances of biomaterial on the column with silica gel L 100/160 mcm is demonstrated. IR-spectrophotometric methods and high performace liquid chromatography with a detector of photodiode matrix are proposed for identification and quantitation of furadan in blood and urine specimens.
