阔叶树皮覆盖物对铅的吸附具有良好的物理化学性质。通过批量试验获得了铅在地膜中的吸附系数。Freundlich模型的结果不如Langmuir模型的结果一致。此外，还设计了一个实验室规模的覆盖可渗透反应墙(PRB)系统来处理受铅(II)污染的地下水。使用覆盖层的覆盖PRB系统潜在地可以用于地下，以经济高效的方式将铅(II)就地转化为环境可接受的形式。从铅(II)穿透曲线看，流量越大，地膜饱和越快。
Hardwood bark mulch has good physicochemical properties for the adsorption of lead (Pb(II)). Batch tests were conducted to obtain the sorption coefficient of Pb(II) in mulch. The results of the Freundlich model were not in as good agreement as for the case of the Langmuir model. In addition, a laboratory-scale mulch permeable reactive barrier (PRB) system was designed for the treatment of Pb(II)-contaminated groundwater. The mulch PRB system, using a mulch layer, can potentially be used in the subsurface for cost-effective and in situ transformation of the Pb(II) into environmentally acceptable forms. From the Pb(II) breakthrough curve, the mulch becomes saturated more quickly at higher flow rates.
