  • 摘要: 以黄河三角洲湿地土壤为对象,研究菲和苯并[a]芘(BaP)在土壤中的吸附特性.结果表明:菲和BaP在黄河三角洲地区湿地土壤的吸附速率都较快,均能在48h内达到平衡;土壤对菲和BaP的吸附等温线均呈线形,能较好地符合线性和Freundlich方程,样品经H2O2处理后对PAHs的吸附量明显降低,表明土壤中有机与无机矿物组分在吸附过程的作用不同;湿地土壤对多环芳烃的吸附明显存在固体效应,随着土壤颗粒物粒径和体系离子强度的增大,土壤的吸附容量都在降低.
    Abstract: Polycyclic aromatic hydrocarbons(PAHs) sorption on wetland soil in Yellow river delta was studied. The results indicated that sorption isotherms of wetland soil and samples treated by H2O2 were linear;PAHs sorption isotherms could be well fitted to Linear and Freundlich equations. Different soil concentration, soil particles magnitude and system Ca2+ concentration influenced PAHs sorption process. With particles magnitude and Ca2+ concentration increasing, adsorption capacity(Kd) of PAHs gradually decreased.
