Black Carbon and Kerogen in Soils and Sediments: Isolation, Characterization, and Their Roles in the Sorption of Organic Pollutants

0121956黄：拟议研究的目的是研究土壤中的黑碳和干酪根对有机污染物吸附的作用。这项研究的目标是：(1)建立分离和分离黑碳和干酪根的综合化学程序；(2)对分离的物质进行表征；(3)测量分离物质和原始土壤对疏水有机物(HOCs)的吸附和解吸；(4)建立吸附、黑碳和干酪根的含量和性质以及所测试的HOCs性质之间的预测关系。这项研究可以更好地了解土壤有机质的化学组成以及土壤中HOCs的结合、封存和衰减机制。这可能会影响我们对污染物的去向和迁移以及污染物在环境中的衰减的知识。***

0121956 Huang The objective of the proposed research is to study the role of black carbon and kerogen in soils on the sorption of organic pollutants. The goals of this research are to: (1) develop a comprehensive chemical procedure for the isolation and fractionation of black carbon and kerogen, (2) characterize the isolated materials, (3) measure hydrophobic organic chemicals (HOCs) sorption and desorption for the isolated materials as well as the original soils, and (4) establish a predictive relationship among sorption, the contents and properties of black carbon and kerogen, and the properties of the tested HOCs. This research could provide improved understanding of both the chemistry of soil organic matter and the mechanisms for the binding, sequestration, and attenuation of HOCs in soils. This could have impact on our knowledge of contaminant fate and transport, and pollutant attenuation in the environment. ***
