A technique for the determination of food dyes using reversed-phase thin-layer chromatography on octadecyl-modified silica is described. A solvent system containing 5.0% aqueous sodium sulphate solution enables good separation of the food dyes. Their separation is dependent on the pH of the solvent
The similarity of our results to those of RAGAZZI, VERONESE AND GIACOBAZZIG suggests that the "magnesium oxide heavy hydrated" used by these authors had in fact undergone at least: partial conversion to the hydroxide before use. For a detailed discussion of the chemical hydration of magnesium oxide,
