Towards a Molecular-Scale Understanding of Sorption of Organic Pollutants to Soil

点击翻译按钮获取中文摘要

The toxicity, mobility and persistence of organic pollutants in soils are in large part controlled by their sorption to soil organic matter. The chemical nature or quality of the organic matter affects not only the amount of chemical sorbed, but also the reversibility of sorption and the rate of sorption and desorption. Until now, only bulk measures of soil organic matter chemistry have been considered in sorption studies. This project introduces novel spectroscopic techniques that for the first time identify the chemical environment of sorbed molecules at the molecular scale. This will enable better prediction of pollutant transport and degradation.
