A laboratory experiment was conducted to study the effect of different levels of organic C on adsorption and desorption of Pb and Ni in soils. The adsorption data were fitted to Freundlich equation for adsorption and desorption and adsorption isotherms were well described. The data showed that Pb was adsorbed in higher amounts than Ni as evident by higher adsorption percentage and distribution coefficient. Adsorption of both Pb and Ni increased with increasing levels of organic C, but it decreased with increase in metal concentrations irrespective of organic C levels. The desorption of Pb and Ni increased with increase in their concentrations and decreased with increase in organic C levels of soil.
