✦ Synopsis

Ethylenediamine tetra-acetic acid disodium salt dihydrate was used as an impregnating reagent to resolve some cephalosporins. Both changes in the concentration of the impregnating reagent and in the composition of the mobile phase influenced the resolution. Three new solvent systems (I) propionic acid:2-propanol:water (6:3:3, v/v/v), (11) 2-prapano1:water:ethyl acetate (5:3:3, v/v/v) and (111) n-butano1:water:acetic acid (5:4:2, v/v/v

## Abstract Cephalosporin antibiotics were separated on thin layer plates impregnated with transition metal ions, Mn^2+^, Fe^2+^, Co^2+^, Ni^2+^ and Cu^2+^, using different concentrations. Various solvent systems were developed for the study and were used for separation of these analytes. Impregnat
