Abstract

Abstract: The adsorption thermodynamics of loam paddy soil to adsorb Cu , Ni , Pb and As were studied. The results show that the adsorption thermodynamics accords with Freundlich equation. The order of adsorb ability is Pb " Cu ＞ As ＞ Ni. The adsorbing ability is not affected by the coexisting elements. According to Langmuir equation the chemical capacities of the four elements were calculated.

Key words: loam paddy soil, copper, nickel, lead, arsenic, adsorption
