      Lipophilicity of some preservatives estimated by RP-TLC using stationary phases with different polarity
      Dorina CASONI*, C. SARBU (*Department of Analytical Chemistry, Faculty of Chemistry and Chemical Engineering, Babes-Bolyai University, Arany Janos Str. No 11, 400028 Cluj-Napoca, Romania)

      Chromatographia 70 (7-8), 1277-1282 (2009). HPTLC of preservatives on three stationary phases of different polarity RP-18, RP-18W and cyano phase, with methanol – water mixtures in different volume proportions. The resulting RM values showed a linear decrease with increasing methanol concentration of the mobile phase (determination coefficients for all stationary phases were >0.98). The retention behavior of the preservatives on RP phase is in good agreement with their polarity. Principal component analysis showed that for all three stationary phases the same lipophilic interactions take place.

      J. Planar Chromatogr. 23, 250-254 (2010). TLC of 30 food additives (aldehydes, organic acids, esters and alcohols, and various sodium salts) on titanium(IV)silicate ion-exchanger with 10 different mobile phases e. g. methanol, heptane - diethylether 41, aqueous ammonia - methanol - ethyl acetate 136, methanol - aqueous ammonia 91, methanol - ethanol 173, 0.5 M ammonium sulfate solution, 0.25 M, 0.5 M and 0.1 M potassium bromide solution, and phosphate buffer pH 2.5 in a twin-trough chamber without chamber saturation. Detection by spraying with 1 % iron chloride solution, 0.5 % potassium permanganate and 3 % barium chloride solution 11, 1 % ninhydrin in ethanol, 2 % phosphomolybdic acid in ethanol, and 5 % potassium dichromate in concentrated sulfuric acid. The study shows that the quality of separation depends to a large extent on the mobile phase, and selectivity is achieved by varying the composition of the mobile phase.
