✦ Synopsis

TLC separation of glucose, maltose, lactose, sorbitol and sucrose on silica gel plates impregnated with transition metal ions, Cu(II), NI(II), Zn(I1) or Cd(II), has been achieved. The identification is very distinct by using KMnO, (0.5%) in 0.1 M NaOH as the spray reagent. Two new solvent systems, (A) n-PrOH-H,O (8:4, vlv), and (B) i-PrOH-H,O (8 : 4, vlv), were worked out.

## 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
