Abstract

The separation and quantitation of organic sulphur compounds were investigated by thin-layer chromatography (TLC) on silica gel layers containing a mixed fluorescent material. The separation of dialkyl disulphides, alkylxanthates and thioureas was performed successfully by reversed-phase TLC using liquid paraffin as the stationary phase. Thiurams and aromatic disulphides were well separated by adsorption TLC. The non-destructive in situ quantitation of these compounds on chromatographic plates was achieved by plotting the logarithm of the amount of compound against the square root of the area of the spot revealed under an ultraviolet lamp.
