Abstract: 

This research was carried out to study the sorption of lead (Pb) and cadmium (Cd) at surface and sub-surface horizons of ten Palygorskitic soils in eastern Isfahan province. Physical, chemical and mineralogical properties of the selected soils were measured. Sorption characteristics of Pb and Cd were estimated from sorption isotherms using Langmueir, Ferundlich and linear equations. According to the mineralogical results, smectite, mica, palygorskite, chlorite, kaolinite and quartz exist in all of the studied soils. Ferundlich and linear adsorption isotherms and Ferundlich, Langmueir and linear adsorption isotherms were able to describe the lead adsorption and cadmium adsorption, respectively, Ferundlich isotherm showed higher R2 for both of the elements. Parametern in Ferundlich equation for Pb and Cd was in the range of 0.22-1.52 and 1.95-4.61, respectively. Distribution coefficient (KF) for Pb and Cd was in the range of 2679-114815 and 353-1369 Lkg-1, respectively. Maximum sorption of cadmium (b) was in the range of 1250-2000 mgkg-1. The constant related to binding energy (k) was in the range of 0.30-2.50 Lmg-1 for cadmium. In linear model, distribution coefficient (Kd) for Pb and Cd was in the range of 4188-64605 and 33-678 Lkg-1, respectively. In general, lead sorption was higher than cadmium sorption in the soils of the area. Correlation coefficients between sorption isotherms parameters and soil physico-chemical properties showed that calcium carbonate equivalent, organic mater, cation exchange capacity and clay percentage are the most important soil properties for Pb and Cd sorption.
