      Comparison of hematoporphyrin with other fluorogenic agents for the detection of cationic surfactants and lipids after separation by HPTLC
      J.H. AIKEN, C.W. HUIE*, (*Dept. of Chem., State Univ. of New York at Binghamton, Binghamton, NY 13902-6000, USA)

      J. Planar Chromatogr. 5, 87-91 (1992). Comparison of ANS (8-anilo-1-naphthalene sulfonate, ammonium salt), rhodamine B, nile red, dichlorofluorescein with hematoporphyrin; visual comparison under UV 366 nm. Limits of (visual) detection (LOD) were 10-20 ng for the cationic surfactants, and 5 and 10 ng, respectively, for the phospholipids (sphingomyelin and lecithin) and cholesterol.

      TLC separation of rare earths using di(2-ethylhexyl)dithiophosphoric acid as complexing agent
      Maria-Loredana Soran*, T. Hodisan, M. Curtui, D. Casoni (*National Institute of Research and Development for Isotopic and Moleculer Technology, 72-103 Donath Street, 400293 Cluj-Napoca, Romania)

      J. Planar Chromatogr. 18, 160-163 (2005). TLC of rare earths (La(III), Ce(III), Pr(III), Sm(III), Gd(III), Er(III)) on silica gel and silica gel impregnated with 2.5 M ammonium nitrate with different mixed mobile phases containing di(2-ethylhexyl)dithiophosphoric acid as a complexing agent. The best results were obtained by use of ethyl methyl ketone - tetrahydrofuran - 1 M di(2-ethylhexyl)dithiophosphoric acid 17:8:1. Double development was used to obtain better separation of consecutive rare earths.

      Selective separation of dodecyltrimethylammonium bromide from other cationic and nonionic surfactants
      A. MOHAMMAD*, N. HAQ (*Analytical Research Laboratory, Department of Applied Chemistry, Aligarh Muslim University, Aligarh-202002, U. P., India;

      J. Planar Chromatogr. 20, 347-351 (2007). TLC of DTAB on soil, silica gel, alumina, and kieselguhr with fifteen mobile phases, such as aqueous solutions of ammonium sulfate and urea, with chamber saturation for 10 min. Detection by spraying with modified Dragendorff reagent. Among the systems studied the best system for selective separation of DTAB from multicomponent mixtures of other surfactants was kieselguhr - 0.1 M ammonium sulfate. Semi-quantitative determination by spot-area measurement.

      Separation of some nonylphenyl ethylene oxide oligomers according to the length of the ethylene oxide chain
      T. CSERHATI, (Central Res. Inst. for Chem., Hungarian Acad. of Sci., P.O. Box 17, H-1525 Budapest, Hungary)

TLC of non-ionic surfactants (e.g. nonylphenyl ethylene oxide oligomers) according to the length of the ethylene oxide chain on aluminum oxide with chloroform - acetonitrile mixtures. The optimum separation of pairs of surfactant oligomers with the longest ethylene oxide chains required eluents of the highest strength (highest acetonitrile concentration).

      Acta Chrom. 17, 272-291 (2006). TLC on silica gel with 0.1 M glutamic acid – methanol – acetone 1:1:1 has been found to be highly suitable for separation and identification of cationic and non-ionic surfactants. Visualization by use of Draggendorf reagent or iodine vapour. Spectro-photometric determination of tetradecyltrimethylammonium bromide at 670 nm after the spot extraction. The method has been used for identification of tetradecyltrimethylammonium bromide and Triton TX-100 in saline water, river water, and domestic waste water. The effects of sample pH, polarity of the alcohol and nature of the amino acid in the mobile phase, and the presence of alumina, kieselguhr, or cellulose in the silica gel layer have been examined.
