      Simultaneous identification of mixtures of inorganic cations by two-dimensional thin-layer chromatography
      T. YOSHINAGA*, T. MIYAZAKI, H. AKEI. (Dept. of Chem., Fac. of Eng., Kyushu Inst.. of Techn., Sensuicho, Tobata-ku, Kitakyushu, 804 Japan)

      J. Planar Chromatogr. 11, 295-299 (1998). 2D-TLC of twenty inorganic cations on cellulose with1) 1-butanol saturated with a 1:1 mixture of 3 M nitric acid and 1 M HCl and 2) methanol - 36% HCl 10:3. 22 color reagents were used for detection. The twenty cations were chosen from the group of inorganic cations studied in the systematic qualitative analysis in introductory undergraduate chemistry courses.

      Qualitative identification of metal ions in honey by two-dimensional thin-layer chromatography
      A.J.M. HORVAT*, Z. SOLJIC, M. DEBELIC, (*Dept. of Anal. Chem., Fac. of Chem. Eng. and Techn., Univ. of Zagreb, Marulicev trg 20, 10000 Zagreb, Croatia)

      J. Planar Chromatogr. 15, 367-370 (2002). 2D-TLC as screening method for Al, Cr, Cu, Ni, Mg, Zn, Mn, Pb, Sn, and Fe in honey with different mobile phases and detection reagents. The best separation was achieved on cellulose with acetonitrile - hydrochloric acid - water 73:15:12 in the first direction and 2-pentanol - acetonitrile - hydrochloric acid 3:2:5 in the second direction. A mixture of quercetin and dimethylglyoxime (prepared by dissolving 0.1 g quercetin in 100 mL 2-propanol and 1.0 g dimethylglyoxime in 100 mL ethanol, with dissolution by heating), and exposure to ammonia vapor was used for the visualization of the spots. This reagent mixture produced intensely colored spots for all the ions tested and enabled their identification at concentrations ranging from 50 to 1000 ng per spot. Simple, efficient and rapid method.

      Thin layer chromatography of inorganic ions on blended inorganic ion-exchangers with tributyl phosphate – formic acid as mobile phase
      A. MOHAMMAD*, R. YOUSUF, Y. HAMID (*Anal. Res. Lab., Dept. of Appl. Chem., Fac. of Eng. and Techn., AMU, Aligarh-202002, India)

      Acta Chrom. 11, 171-182 (2001). The chromatographic behaviour of some cations (Ni2+, Co2+, Cd2+, Cu2+, UO22+, VO2+, Fe2+/3+, Al3+, Th4+, Mo6+, W6+, Pb2+, Hg+/2+, Bi3+, Ag+, and Tl+) and anions (CrO42-, Cr2O72-, IO3-, IO4-, BrO3- SCN-, Fe(CN)63-, NO2-) was examined on layers prepared from 1:9 mixtures of a synthetic inorganic ion-exchanger (stannic arsenate or tin(IV) molybdosilicate) with silica gel, alumina, or cellulose with 1 % methanolic tri-n-butyl phosphate – 1 M aqueous formic acid 1:4 as mobile phase. Several binary cation separations of analytical interest were achieved. The metal ions were detected by use of conventional spot-test reagents. Separation of IO3- from NO2- and BrO3- under the same conditions, detection with 0.2 - 0.5 % diphenylamine in 2 M H2SO4. For quantitative determination the region corresponding to IO3- was isolated from the plate and extracted with 1.0 M hydrochloric acid. 1 % potassium iodide and conc. hydrochloric acid were added to the extract and the mixture obtained was titrated against Na2S2O3.
