Spectrophotometric determination of selenium with cyclohexanone.
Selenium (2-100 mug) can be determined directly in the aqueous phase by formation of the ketone-chloro complex with cyclohexanone in ~7M hydrochloric acid from either selenium(IV) or selenium(VI), the reaction being brought to completion by heating for 5 min in a boiling water-bath.
