Study on Desorption Behavior of Trichloroethylene on Different Soils

  • 摘要: 采用w(TOC)(TOC为总有机碳)不同的2种天然土壤以及用H2O2去除大部分软碳和高温灼烧去除全部有机碳后所得到的6种土样为吸附剂,以TCE(三氯乙烯)为研究对象,考察了有机碳含量及组成、矿物质、初始ρ(TCE)等因素对TCE解吸行为的影响,并比较了吸附解吸异质性大小. 结果表明,解吸平衡时6种土样的TCE解吸量不到相应吸附量的25%;TCE在6种土样上的解吸等温线表现出更高的非线性特征. 所有土样都表现出一定程度的吸附解吸异质性,HI(异质性指数)均大于2.0,其中H2O2氧化土样的异质性更高(HI>4.0). 2种原土中有机碳和矿物质对TCE解吸的平均贡献率分别为74%和26%,而H2O2氧化后的2种土样中该值分别为68%和32%;初始ρ(TCE)越高,矿物质的解吸贡献率相对越低. 此外,TCE的解吸量与土壤矿物质中孔和微孔的体积也有一定的关系.
