Chromatographic Separation of Some Inorganic Ions on Silica-Gel Pyridinium Tungstoarsenate Impregnated Thin Layer Plates

Abstract

A scheme for the TLC separation of twelve inorganic ions on Silica Gel-Pyridinium Tungstoarsenate impregnated plates by using a mixture of butanol-acetic acid-ethyl alcohol-acetone-water (60:10:30:40:10) or isopropanol acetic acid-acetone (60:5:35) as developing system and employing 0.5% dithizone in chloroform as visualization reagent is described. Examples of separations of binary, ternary and pentnary mixtures are given.
