The Experiment on the ionic interference of some common metals like Ca, Zn, Cu and Ni on Pb adsorption was conducted in order to elucidate the nature of binding of these ions to the soils in the presence of Pb. Six surface soil samples representing different soil series and types located in various contaminated areas of Coimbatore district were collected and analyzed for any ionic interference on adsorption of lead. The results revealed that, binary combination of Ca2+ combined with Ni2+ had greater competitive effect on Pb adsorption. The results of such experiments give an understandable trend of the effect of the these ions, which could be explained more on the fundamental physical properties of these ions based on their electronic configuration, stability constants and poly electrolyte effect Top Keywords Ionic interference, adsorption.
