Abstract
THE most sensitive chemical method of detection of iodine-containing substances on paper chromatograms is the application of the ceric sulphate–arsenious acid reaction1. By the use of this method the iodine-containing substances are indicated by white spots on a yellow background. Fletcher and Stanley2 obtained white spots on a brown background by spraying such chromatograms with 1 per cent o-phenylenediamine in acetone.
