Sažetak
The chromatographic behaviour of some substituted phenolic compounds on silica gel layers impregnated with Al(III) and Cu(II) was studied. Addition of metal ions gives very good separations of some structural isomers. In order to establish whether any improvment in the separation could be achieved by varying the concentration of impregnant, three different concentrations of CuSO4 . 5H2O and AlCl3 . 6H2O (1, 2 and 4%, w/w) were used. A very good separation of hydroquinone and resorcinol on silica gel layers impregnated with CuSO4 was achieved. Aminophenols can be successfully separated using silica gel layers modified by CuSO4 addition. The optimum resolution of meta and para isomers was achieved on silica gel containing 0.51 % Cu(II) ions (2% CuSO4 . 5H2O).
