Synthetic zeolites A and X as stationary phases in thin-layer chromatography
The possibility of using synthetic zeolites A and X as stationary phases in thin-layer chromatography has been investigated and the method of preparing layers from crystalline zeolites and their gels determined, as was the possibility of separating certain mixtures on the layers obtained. Experiments were performed simultaneously on layers from zeolites A and X dried at room temperature and on layers activated at 120°C, and also on layers from amorphous forms but in this case only on those dried at room temperature. Dyes and inorganic cations were used as test substances. On the basis of the results obtained it has been established that only the crystalline compounds can be successfully used as thin layers for the separation of organic compounds.
