摘要/Abstract

摘要： 分析了青紫泥和黄筋泥两种不同地区的水稻田土壤及其提取物对亲水性有机物腐殖酸和疏水性有机污染物芘的吸附性能，得出以下实验结果：水稻土壤类型对腐殖酸或芘的吸附持留能力无显著影响；土壤及其提取物对腐殖酸的吸附性能强弱依次为原土>黑碳>无机矿物；对芘的吸附性能原土和黑碳比较接近，Freundlich方程及其吸附解吸分配系数（Kf）能更好地反映出二者对芘的吸附性能；水稻土壤及其黑碳的亲水/疏水性能是二者对腐殖酸和芘吸附性能强弱的主要决定因素.

Abstract: Adsorption and persistence capacity of humic acid and pyrene on two kind of paddy soils had no obvious difference. The order of adsorption and persistence capacity of humic acid was that soil > black carbon > cauterant soil. It was similar between the soil and its black carbons on the adsorption capacity of pyrene. The Freundlich equation and partition coefficients (Kf) could reflect it better. Hydrophobic or hydrophilic properties of paddy soil and its black carbons were the main factors on the adsorption proerties of humic acid and pyrene.

Key words: black carbon, humic acid, pyrene, adsorption property, paddy soils, black carbon, humic acid, pyrene, adsorption property
