J. Planar Chromatogr. 13, 210-216 (2000). TLC of fifteen metal ions on silica gel with solutions of cetyltrimethylammonium bromide as mobile phase. (1:2 CTAB-ethanol) - water 1:99 was identified as the best mobile phase for rapid separation of Zn, Cd, Co, and Hg. Semiquantitative determination of Ni and Zn by visual comparison of color intensities.

Chromatographia 62 (1-2), 91-97 (2005). Silica gel impregnation with polyethylene glycol of different molecular mass (400, 1000, 1540, 4000, and 5500) was investigated for salting-out thin-layer chromatography of 15 mixed aminocarboxylato Co(III) complexes using eight ammonium sulphate solutions as mobile phases. Regularities established earlier for non-impregnated adsorbents are also valid in this work. Polyethylene glycol of high molecular mass increases the hydrophobicity of the adsorbent. Positive linear dependence of RM values and of salting-out efficiency on average polyethylene glycol molecular mass was usually observed. In contrast with non-impregnated silica gel, separation was achieved between complexes with the smallest hydrocarbon groups.

Anal. Letters 18, 1783-1788 (1985). TLC of anions on silica with a) 0.1 M tartaric acid, b) 0.1 M formic acid, c) 0.1M oxalic acid, d) 0.1 M succinic acid. Detection by spraying with 0.1 M fresh silver nitrate.

J. Liquid Chromatogr. 6, 1253-1264 (1983). TLC of 47 metal ions, binary and ternary mixtures e.g. Be2+ - Mg2+, Zr4+ - Ca3+, Th4+ - Ce4+, Th4+ NO2+; Cr3+ - NO6+, W6+, Sb3+ - Bi3+ - Ca2+, Ag+ - Cu2+ - Ca2+ on stannic arsenate with 0.00001 -5 M HCl. Detection with conventional spot test reagents.

J. Chromatogr. Sci., 26, 325-330 (1988). Investigation of the chromatographic behavior of inorganic ions on Sephadex G-25 with acetone - water mixed eluent system in TLC and CC. Emphasis on the effects of eluent electrolyte and of the solvent compositions inside and outside the gel beads. Evaluation of the partition effect on the retention mechanism for different salts. Proposal of a theoretical model interpreting the effect of the background eluent ions on the capacity factors of the analyte ions.

Separation of inorganic ions on layered double hydroxides. J. Planar Chromatogr. 12, 378-382 (1999). TLC of 26 inorganic cations and 17 anions on LDH (layered double hydroxides) layers developed with 32 mobile phases. LDH layers were prepared by addition of magnesium or aluminium nitrate solutions to a solution of sodium hydroxide and sodium carbonate in water. Detection by spraying with 14 different detection reagents. Separations of one ion from several other ions as well as ternary and binary separations have been developed.

J. Planar Chromatogr. 27, 84-87 (2014). TLC of Cu (1), Sn (2), Pb (3), Fe (4) and Ni (5) in Cu-alloys on microcrystalline cellulose with methanol - hydrochloride acid - water 12:7:1. Detection by spraying with quercetin solution (0.1 %), then with a solution of dimethylglyoxime (1 %), and finally exposure to ammonia vapor. The hRF values for (1) to (5) were 73, 93, 55, 85, and around 60 (Ni (5) was detected in only one Cu-alloy and in pure iron).

Anal. Letters 18, 1549-1553 (1985). TLC of Tb, Ti, Zr, Y and 7 lanthanides on cellulose, impregnated with bis-(2-ethylhexyl) orthophosphoric acid - trioctyl phosphine oxide 83:17, with methanol - nitric acid - acetyl acetone 20:15:5. Visualization by first spraying with 1% alcoholic solution of alizarin, then exposing to NH3 vapors.
