Movement of Trace Elements in Soils Using Thin-Layer Chromatography

Abstract

The effect of pH, organic matter, autoclaved soil, CaCO₃and extracts of the different oil-cakes on the mobility of trace elements by employing soil thin-layer chromatographic technique has been studied. Removal of organic matter from the soil increases the movement of trace elements. Similarly, with the increase in the concentration of oil-cake extracts the mobility of trace elements increased. However, autoclaving the soil or addition of CaCO₃ increases the frontal R_f values of certain trace elements and not that of others.
