Acta Chrom. 11, 196-203 (2001). The effects of the stationary and the mobile phases on chromatographic behaviour in the separation of water-insoluble complexes of diethyldithiocarbamate with Cd2+, Co2+, Cu2+, Fe2+, Hg2+, Mn2+, and Pb2+ have been studied by TLC with polar adsorbents (silica gel, previously activated for 40 min at 110 ºC, and neutral aluminum oxide 60 Type E, activated for 4 h at 150 ºC) with benzene - chloroform after chamber saturation for 2,5 h. The proportion of the components of the mobile phase was varied. Visualization by spraying with 5 % aqueous solution of CuSO4 to form a more durable yellow–green chelate (436 nm). The results obtained show that metal ions in the form of their chelates with DDTC can be separated under the presented conditions.

J. Planar Chromatogr. 30, 97-105 (2017). Review of current applications of room temperature ionic liquids on planar chromatography as mobile phases. Methylammonium, ethylammonium, propylammonium, isopropylammonium, butylammonium, s-butylammonium, dipropylammonium, tributylammonium were reported to be used as replacements for organic solvents in binary systems. As mobile phase additives, room temperature ionic liquids were used for the separation of peptides and basic drugs in both normal phase and reversed phase chromatography with an emphasis on their role as masking agents. The authors suggested that given the large number of possible cation and anion combinations, systematic methods that characterize solvation properties for both ionic liquids and organic solvents are required.

After developing to 5 cm the wet plate was dipped 3 times into a solution of Triton X 100 - chloroform 1:4 with evaporation of the solvent in between by storing the plate in the dark for 15 min. at 20°C. Quantification by measuring the fluorescence at 560 nm. Dipping in paraffin oil enhances and stabilizes fluorescence.

Chinese J. Chem. Reag. (Huaxue Shiji) 11, 367-368 (1989). TLC on silica with butanol – methyl iso-butyl ketone – P20 – hydrochloric acid 140:100:15:18 for Au, Pd and Pt, Ru, Ir and Rh, and 140:100:15:1 for Pt and Pd. No interference by other noble metals observed.

J. Planar Chromatogr. 3, 422-424 (1990). The possibility of using TLC for the simple and rapid separation of gold(III), selenium(IV) and tellurium(IV) is demonstrated, and the behavior of the ions chromatographed on alumina with aqueous solutions of both organic and inorganic acids is discussed. The mobile phases investigated included HCl, HBr, H2SO4, H3PO4 and HNO3 and aqueous solutions of various organic acids, over a wide range of concentration.
