Abstract: Filed investigation and labratory analysis was used to research the effects of calcium carbonate and clay particle on accumulation capacity of heavy metals in contaminated soils.The results showed that the accumulation capacity of heavy metals in contaminated soils is increased with the increase of calcium carbonate content,that is calcium carbonate is one of the main effect of accumulation capacity of heavy metals in contaminated soils.Pseudo two order kinetic equation is the best one to fit the adsorption kinetics process and we will know that the average adsorption capacity of heavy metals is lime soil > yellow soil and the average adsorption rate is yellow soil > lime soil.
