      On plate resolution of three-component mixture of cationic surfactants with mixed aqueous-organic eluents containing formate ion
      A. MOHAMMAD*, S. BHAWANI (*Analytical Research Lab., Dept. of Applied Chemistry, Faculty of Eng. & Tech., Aligarh Muslim University, Aligarh, UP, India)

      Separation Science and Technology 44, 1007-1021 (2009). A TLC method for mutual separation of three longchain aliphatic quaternary ammonium halides (cationic surfactants) is reported. TLC of dodecyltrimethyl ammonium bromide (DTAB), tetradecyltrimethyl ammonium bromide (TTAB) and hexadecyltrimethyl ammonium chloride (HTAC) on laboratory made TLC plates coated with Kieselguhr (0.25 mm), with methanol - 10 % sodium formate 3:7 as mobile phase. Detection with modified Dragendorff reagent comprised of solution A (containing bismuth subnitrate and KD) and solution B (containing barium chloride). Solutions A and B were mixed 2:1. The compounds appeared as orange-coloured spots. The effects of alcohols (ethanol, n-propanol), substitution of the formate ion by benzoate and acetate ion, different adsorbents (silica gel, aluminum), and the interference of metal ions ( Cu2+, Zn2+, Hg2+, Co2+, Pb2+) on the resolution of the three surfactants was studied. The limits of detection of DTAB, TTAB, and HTAC estimated were 3.3, 3.1, and 2.8 µg/zone respectively. The method was applied for separation of these compounds in water samples.
