| 摘 要： | 研究了BDE-28在3种不同有机质含量的天然土壤上的吸附行为,包括吸附过程动力学和热力学等温线.结果表明,双室一级动力学模式较单室一级动力学模式更适于描述BDE-28在天然土壤上的吸附过程动力学特征,尤其是在吸附初始阶段(0～25 h).快吸附自吸附初始到表观吸附平衡的整体吸附过程中占据优势地位,而慢吸附的贡献率则逐渐...

| Abstract: | The sorption kinetics and isotherms of BDE-28 on three natural soils with different soil organic matter fractions(fOC) were investigated.The results indicated that a two(fast and slow)-compartment first-order model was more appropriate for describing the sorption kinetic data,compared to a one-compartment first-order model,especially in the initial sorption stage within 25 h.The fast sorption was predominant during the whole sorption process from beginning to the apparent sorption equilibrium;while the cont... |
