锌、铅污染是长期以来备受关注的公共环境问题。垃圾渗滤液中含有Zn（II）和Pb（II）等重金属，这些重金属通常与地下水污染有关，特别是在发展中国家。膨润土能有效地提高粘土的膜性能，使填埋场衬垫对污染物的迁移具有更好的阻隔性能。在这项研究中，5%的钠膨润土与当地可获得的草粘土修正被用来评估对重金属锌和铅的膜行为。通过0.5、1、5、10和50 mM浓度的Zn（II）和Pb（II）溶液获得化学渗透效率系数ω。
Zinc and lead pollution are public environmental issues that have attracted lots of attention for a long time. Landfill leachate contains heavy metals, such as Zn(II) and Pb(II), which are usually related to thepollution of groundwater, especially in developing countries. Bentonite has been proven to be effective in enhancing the membrane property of clay, by which landfill liners can have better barrier performance towards the migration of contaminants. In this study, 5% sodium bentonite amended with locally available Fukakusa clay was utilized to evaluate the membrane behavior towards the heavy metals zinc and lead. The chemico-osmotic efficiency coefficient, ω, was obtained through Zn(II) and Pb(II) solutions with different concentrations of 0.5, 1, 5, 10, and 50 mM. According to the results,
