| 摘 要： | 为阐明底泥表面附着生物膜在内分泌干扰物迁移转化中的作用,对生物膜在底泥吸附乙炔雌二醇(EE2)、双酚A(BPA)和壬基酚(4-NP)过程中的作用机制进行研究。结果表明,BPA、EE2和4-NP的有机物标准分配系数(koc)为101.78~103.02L/kg,经H_2O_2处理所得底泥中EE2的有机物标准分配系数(102.32L/kg)大于未经处理的底泥(102.19L/kg)。建立了两阶段吸附(快速吸附和慢速吸附)动力学模型(r~20.95),模型拟合结果显示,在吸附过程中,快速吸附发挥了主要作用,而慢速吸附则决定了反应程度。底泥表面附着生物膜会阻碍污染物向底泥的传质行为,并且对底泥的吸附能力没有促进作用。
