      Study of the absorption characteristics of a zeolite support in normal and reversed-phase Thin-Layer Chromatography
      T. CSERHÁTI (Institute of Materials and Environmental Chemistry, Chemical Research Center, Hungarian Academy of Sciences, P. O. Box 17, 1525 Budapest, Hungary; tevi@chemres.hu)

      J. Planar Chromatogr. 20, 381-384 (2007). Study of the retention behavior of 36 synthetic dyes in adsorption and reversed-phase TLC on zeolite layers with n-hexane, tetrahydrofuran, and bidistilled water. Significant linear correlations were found between the retention of the dyes chromatographed with the different mobile phases, proving the regular retention behavior of the analytes. No linear relationship was found between the physicochemical properties of the dyes and their retention, suggesting the separation capacity of zeolite differs markedly from that of silica and silica coated with hydrophobic ligands.

      (Study of sulfur fine particles as the stationary phase for thin-layer chromatography/Fourier transform infrared spectroscopy (TLC/FTIR) hyphenated technique) (Chinese)
      X. FAN (Fan Xiaokun), Y. JIANG (Jiang Ye), Z. SONG (Song Zengfu), Y. WEI (Wei Yongju)* (*Coll. of Chem. & Materials Sci., Hebei Norm. Univ., Hebei, Shijiazhuang 050024, China)

      Chem. J. of Chinese Univ. 35 (4), 741-745 (2014). TLC is a rapid, simple, efficient, economic and widely used method with great advantages but some limitations in the detection of unknown groups. IR is a universal detection technique with advantages in the detection of colorless, non fluorescent substances. For successful application of TLC/FTIR the selection of the proper stationary phase is important. In this study sulfur fine particles were successfully employed as the coating for narrow band plates. Sulfur fine particles with the average size of 500 nm were produced by reaction of sodium thiosulfate with hydrochloric acid and characterized by XRS. Narrow band plates were coated by precipitation/evaporation technique. TLC of the mixture of rhodamine B and gentian violet on narrow band plates with tetrahydrofuran – methanol – ammonia 16:2:1 with chamber saturation for 10 min. TLC of the mixture of rhodamine B and bromophenol blue on narrow band plates with ethyl acetate – methanol – ammonia 16:1:3 with chamber saturation for 10 min. Both systems achieve complete separation. In situ detection of the separated zones by microscopic reflection infrared spectroscopy. The resulting spectra of the separated zones of rhodamine B, gentian violet and bromophenol blue matched those of the corresponding standards. There were no interfering absorption peaks except for the absorption peak of CO in the mid infrared region. The layer had a considerable ability for separation of mixed samples, therefore, the new type of stationary phase can meet the requirements for analyzing some mixtures by TLC/FTIR hyphenated technique.
