  • 摘要: 土壤/沉积物是环境中有机污染物主要的汇. 由于土壤-沉积物结构和性质的复杂性,有机污染物进入其中,会结合在不同的位点上,赋存状态发生分化,具有不同的物理流动性、生态风险和化学反应活性. 对于土壤-沉积物中有机污染物吸附/解吸的研究是认识其赋存状态并预测其生态风险的重要手段. 本文对于疏水性污染物吸附/解吸及赋存状态的国内外研究进展进行了综述,介绍了对吸附/解吸动力学及机理的认识历程,讨论了吸附剂的化学性质和物理构象、吸附质的性质及浓度、相互作用时间、以及环境条件与复合污染对有机污染物的吸附/解吸行为的影响.
    Abstract: Soils and sediments are the main sink for organic pollutants. Due to the complexity of these natural sorbents, organic pollutants are bound at different sorption sites in soils and sediments, leading to a differentiated existing state. Correspondingly, the sorbed organic pollutants possess different physical mobility, ecological risk, and chemical reactivity. Study on the sorption and desorption of organic pollutants could gain insight into the existing state of sorbed organic pollutants, and help to predict their risk. In this paper, recent studies on the sorption/desorption and existing state of hydrophobic organic compounds were reviewed. The development on the dynamics and mechanisms of sorption and desorption was introduced. The impacts of chemical properties and physical conformation of the sorbent, the characteristics of the sorbates, aging time and pollutant co-exiseence, environmental conditions, and pollutant co-exiseence on the sorption and desorption were discussed in depth.

摘要: 土壤/沉积物是环境中有机污染物主要的汇. 由于土壤-沉积物结构和性质的复杂性,有机污染物进入其中,会结合在不同的位点上,赋存状态发生分化,具有不同的物理流动性、生态风险和化学反应活性. 对于土壤-沉积物中有机污染物吸附/解吸的研究是认识其赋存状态并预测其生态风险的重要手段. 本文对于疏水性污染物吸附/解吸及赋存状态的国内外研究进展进行了综述,介绍了对吸附/解吸动力学及机理的认识历程,讨论了吸附剂的化学性质和物理构象、吸附质的性质及浓度、相互作用时间、以及环境条件与复合污染对有机污染物的吸附/解吸行为的影响.
