J. Planar Chromatogr. 16, 286-288 (2003). TLC of zinc(II) butyrate, zinc(II) isobutyrate, and zinc acetate on silica gel, prewashed with water û methanol, with 2-propanol - water 2:3 and pure redistilled water and on anion exchange layers with dioxane - water 3:2. Detection by derivatization with bromophenol blue, bromocresol green, and thymol blue indicator solutions, directly on the wet layer. Bromocresol green (0.5% solution + 5 mL 0.1 M NaOH) resulted in most sensitive detection of the carboxylates tested. The detection limit for this reagent and butyrate anion was established as 0.03 mg/L. New detection procedure.

J. Planar Chromatogr. 23, 156-161 (2010). TLC of aluminium, silicon and iron on microcrystalline cellulose, on silica gel and combinations with aluminium oxide. Mobile phases used were 1:1, 7:3, 9:1, and 8:2 mixtures of 10 % aqueous solutions of sodium chloride, potassium chloride, potassium bromide, and sodium formate with 10 % aqueous formic acid, and 1:8 mixtures of 1 % aqueous sodium molybdate with 3 %, 4 %, and 5 % hydrochloric acid. Aluminium(III) was detected by spraying with 0.05 % aqueous aluminon (triammonium aurin tricarboxylate). Aqueous potassium ferrocyanide in 10 % aqueous sodium formate solution was used for the visualization of iron(II). Silicon was detected by spraying with 1 % sodium molybdate at pH 0.80-0.92. Quantitative determination by scanning densitometry at 402 nm for silicon, at 528 nm for aluminium and at 620 nm for iron. LOD was 7-10 ppm for aluminium(III), 2-5 ppm for iron(II), and 4-6 ppm for silicon(IV).

Chromatographia 20, 364-366 (1985). Study of TLC behaviour of 49 inorganic ions on cellulose phosphate with binary solvent mixtures consisting of sulfuric acid and an organic solvent. Demonstration of the feasibilities of the separation of multi component mixtures with 0.5 mol sulfuric acid - acetone 8:2. The Rf values of many bivalent and monovalent ions decrease on p-cellulose with an increasing concentration of the organic solvent.

Detection limit 2000 ng. An empirical formula for Rf was presented as a function of atomic number and ionic radius of the separated species and developing reagent.

Chromatographia 25, 989-992 (1988). Reversed-phase TLC of rare earth elements octadecyl-bonded silica with methanol - lactate media. Detection by spraying with 0. 1% aqueous arsenazo (III) or 0. 1% aqueous xylenol orange followed by exposure to NH3. Investigation of the partition chromatographic behavior and the effects of the concentration and pH of lactate solution, methanol concentration and temperature on the migration and the resolution of rare earth elements. The partition system is particularly suited to separate adjacent rare earths of middle atomic weight groups.

TLC of Re, Mo, V, W on Polichrom A (a copolymer of mixed 1,4- and 1,5-di(methacryloyloxymethyl)naphthalene and styrene with starch, dextrin of a polyvinyl alcohol containing 10-14% acetate groups as binder), with 0.5 hydrochloric acid - ethanol 9:1 as mobile phase. Detection by spraying first with a saturated solution of tin chloride in conc. HCl and second with a saturated aqueous solution of ammonium rhodanide.
