摘要(Abstract)：

水/沉积物界面是有机和无机污染物的物理、化学等过程的重要载体和场所。为了探究溴代阻燃剂与重金属在水/沉积物体系的分布规律,以电子垃圾拆解地水体中常见的溴代阻燃剂十溴联苯醚(BDE209)和重金属Pb、Cd为目标污染物,考察了腐殖质对BDE209、Pb和Cd在水/沉积物界面吸附行为的影响。红外光谱分析表明沉积物腐殖质活性基团包括醇、酚和羧基类等官能团;1H核磁共振分析显示沉积物腐殖质主要由碳水化合物与脂肪族类化合物组成。吸附试验结果表明,水体中腐殖质能够促进沉积物表面BDE209、Pb和Cd的释放,BDE209在水/沉积物体系的吸附行为主要受水溶性腐殖质的影响,而对Pb、Cd而言,负载于沉积物表面的碱溶性腐殖质比水溶性腐殖质对其分配行为的作用更显著。此外,沉积物组分对BDE209在水/沉积物体系的分配行为无显著影响;粘土组分对Pb、Cd的富集能力高于砂粒,并且对Pb的富集能力比Cd更为突出。
