Separation and Identification of P-Methoxy Phenacylidene-P-Dimethyl Amino Aniline-cd(II), Fe(III), Mn(II), Cu(II) and Co(II) Complexes by Thin Layer Chromatography

Thin Layer Chromatographic study on separation and identification of metal complexes of p-methoxy phencyclidine-p-dimethyl amino aniline (Schiff Base) with Cd(II), Fe(III), Mn(II), Cu(II) and Co(II) has been carried out. For this, Silica Gel is used as adsorbent and the mixture of complexes was run on thin layer of Silica Gel; the R_f values of the complexes were determined in Methanol, Benzene-Acetone, Nitrobenzene-Methanol and Dioxane. The complexes were separated and were identified by comparing their R_f values and developing time. It was found that the extent of separation of complexes varied considerably with the nature of solvent systems employed and comes in Methanol > Benzene-Acetone > Nitrobenzene-Methanol > Dioxane order.
