Title Determination of 1,2,3,4,5,6-hexachlorocyclohexane (BHC) in air by microdiffusion method
Bibliographic information Dec. 1982, Vol.43, No.12, p.912-914. Illus. 9 ref.
Abstract A simple field technique is described whereby BHC is extracted from a sample in acetic acid, dechlorinated by reaction with zinc and acetic acid and the resultant benzene is volatilised and absorbed in a nitrating mixture by micro-diffusion technique. The m-dinitrobenzene formed is spectrophotometrically determined by the butanone method. The sensitivity and precision of this method is 5Ág▒5.0%.
