The retention behaviour of nineteen phenols has been examined on plain and ethylenediamine tetraacetic acid (EDTA)-impregnated silica gel layers developed with buffered solutions of cetyltrimethylammonium bromide (CTAB). The effect of CTAB concentration and the nature of other additives (alcohols of different carbon-chain length and acetonitrile) on the RF value (or mobility) of the phenols was studied. Among the additives investigated, 5% methanol was found most suitable. Good separations of phenols were possible with 1% CTAB in 50:50:8 (v/v) 0.04 M boric acid–0.04 M phosphoric acid–0.24 M NaOH as mobile phase. Some important separations were achieved experimentally both on plain silica and on EDTA-impregnated layers.
