THE USE OF IMPREGNATED SILICA-GEL LAYERS AND MODIFIED CELLULOSES IN THIN-LAYER CHROMATOGRAPHIC ANALYSIS OF INORGANIC MIXTURES

This review of literature covers salient features on the use of impregnated silica gel layers and modified cellulose layers as applied to the analysis of inorganic mixtures. One hundred and ten references have been cited from the literature published from 1963 to 1993. Although plain silica gel is commonly used for thin-layer chromatography of inorganics, silica gel impregnated layers play an important role for achieving particular separations of analytical importance and are more frequently used than plain adsorbents except for silica gel. Modified celluloses have received proper attention in the recent past, particularly for rare earths.
