摘要: 通过对砂壤水稻土中Cu,Ni,Pb,As 4种元素的单元及复合吸附试验,表明其吸附热力学符合Freundlich方程,吸附能力为Pb>Cu>As>Ni.共存元素对土壤吸附某一元素的能力影响不大;用Langmuir方程粗略地估算出这4种元素在土壤中的化学容量.

关键词: 砂壤水稻土, Cu, Ni, Pb, As, 吸附

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
