本文描述的研究通过实验室规模的平衡和速率测试，研究了活性炭吸附去除有机自由水（OFW）和腐殖酸背景溶液中多氯联苯（PCBs）和毒杀芬的有效性。此外，还进行了络合实验，以评估目标污染物与腐殖酸（HA）之间的关联程度。分散流均匀表面扩散模型可用于预测固定床吸附器去除OFW中多氯联苯的性能。当HA存在时，由于络合和竞争吸附效应，碳容量大大降低，并且由于各种物种的存在，例如未结合的HA和污染物HA络合物，吸附剂动力学变得复杂。包括25个参考文献、表格和图表。

The research described here investigated the effectiveness of activated carbon adsorption for the removal of polychlorinated biphenyls (PCBs) and toxaphene from organic-free water (OFW) and humic acid background solution, using bench-scale equilibrium and rate tests. In addition, complexation experiments were conducted to assess the extent of association between the target pollutants and humic acid (HA). The dispersed-flow homogeneous surface diffusion model was satisfactory for predicting the performance of fixed-bed adsorbers for removing PCBs from OFW. When HA was present, carbon capacity was greatly reduced because of complexation and competitive adsorption effects, and the adsorber dynamics were complicated by the presence of various species such as unassociated HA and pollutant-HA complexes.
