S3>S4>S2>S1. The retention of heavy metals depends on the amount of active calcium carbonate, clay content and surface area of the soil. The values of adsorbed three heavy metals on the five soil samples can be arranged as; Cd > Pb >Ni.
The constants of the four kinetic equations (a, b and r2) were compared for the two concentrations of each metal (Elovich, Modified Frendlich Equation "MFE", Horels and Diffusion). The correlation coefficient between soil criteria and the constants of the applied kinetic models reveals that highly positive correlation between active calcium carbonate, surface area and clay content with a and b constants in Elovich and Diffusion equations.]]>
