“…The applicability of a quadratic relationship between the time of mobile phase motion and the distance from the solvent entry position of the mobile phase and the front of the mobile phase was validated for micellar TLC by Boichenko (2011).The use of a micellar solution as the mobile phase in TLC was first reported by Armstrong and colleagues(1979 "a", "b").Despite distinct advantages, micellar systems have not been extensively used in TLC compared to their use in reversed phase high performance liquid chromatography in various areas (Landy and Dorsey, 1985;Borgerdingand Hinze, 1985;Guermouche et al, 1998;Ihara and Hobo,1993)and in micellarelectrokinetic capillary chromatography (Janini and Issaq, 1992;Fu et al, 1998;and Skocir and Prosek, 1995). Metal ions were successfully separated using anionic surfactant SDS containing amino acids by Mohammad and Sirwal(2002) and SDS with iodides and chlorides from pure soil sample by Mohammad and Jabeen (2003).Various metal ions separated on Titan-Yellow modified resin surfactant solvents (Nabi et al, 2008). Mallah et al, (2010) used SDS surfactant in micellarelectrokinetic chromatographic separation and analysis of uranium, gold and mercury in an environmental ore sample.…”

The analytical potential of Tween-80, a nonionic surfactant used as a mobile phase in the thin layer chromatographic separation of heavy metal cations, is assessed. The surfactant concentrations, acidity and basicity of Tween-80solutions are investigated for the migration behavior of heavy metal cations on aminoplast+ cellulose mixture thin layer. The influence of weak or strong electrolyte and alkanol additives in the surfactant-containing mobile phase on the mobility of heavy metal cations on the aminoplast+ cellulose mixture thin layer is examined.

“…Using a surfactant as the mobile phase gained popularity and became more widely applied due to its operational simplicity, cost effectiveness, relative non-toxicity and enhanced separation efficiency [5][6][7][8]. The use of silica gel and an alumina layer with surfactant mediated mobile phase systems [9][10][11][12][13][14][15] has been used to separate various inorganic species. Number of metal ions was systematically chromatographed on thin layer of urea formaldehyde polymer [16].…”

Thin layer chromatographic method has been developed for the separation of metal ions such as Cr(VI), Cr(III), As(III), Cd(II), Tl(III) and Hg(II) from their two, three and four component mixtures. The separations were performed on thin layer of silica gel 'G' using aqueous l-Alanine as mobile phase. The effect of concentration and pH of mobile phase on the R f values of individual metal ions were studied and the optimum conditions for separation of metal ions from their mixture were determined.

Thin layer chromatography of cationic and nonionic surfactants was performed on kieselguhr 'G' layers. Eight amino acids at three different concentration levels were used as aqueous mobile phase systems to examine the chromatographic behavior of cationic and nonionic surfactants. Among mobile phases used, a 0.01% methionine solution was found most suitable for the separation of cetylpyridinium chloride (CPC) from the mixture of nonionic surfactants on kieselguhr layers. The separation is not influenced by the presence of metal cations as impurities in the sample. None of the dyes, except ammonium purpurate and malachite green, hamper the separation. The exposure of the sample to UV radiation (k = 254 nm) also does not have any adverse effect on the separation of CPC from TritonX-100 and Brij-35. The R F values of surfactants were found to vary marginally on substitution of L-methionine by its D-isomer in the mobile phase or by the change in pH of the mobile phase (0.01% L-methionine) from 2.9 to 8.8. The proposed method can also be used for preparative thin layer chromatography.
