title: Microanalysis of sulphide, sulphite, sulphate and thiosulphate by thin-layer chromatography and ring-colorimetry.
abstract: Clean and rapid analytical separations of microgram quantities of S(2-), SO(3)(2-), SO(4)(2-) and S(2)O(3)(2-) ions have been accomplished by ascending thin-layer chromatography on microcrystalline cellulose with n-propanol-1M ammonia-acetone (30: 20: 2) as the solvent system. The separated species have been determined by ring-colorimetry.
