Storage of wastes leads to severe problems of water pollution and neighboring matrices due to the infiltration of landfill leachate. Uncontrolled landfill and waste storage can lead to groundwater pollution, which can lead to serious health problems for the living. Engineered barriers can be a solution to these pollution problems. The purpose of this study was to develop novel composite materials – clay-based, activated carbon, cement, and PVA polymer. These composites were intended for the containment of waste in landfill. The clay (70–80%) and activated carbon (5–15%) contents were varied to obtain three different geomaterials – GM1, GM2, and GM3. In the preparation of GM3, the content of activated carbon used was higher than for GM1 and GM2, paracetamol removal capacity tested by adsorption, experiments were influenced by parameters such as the adsorbent mass, the initial solute concentration, contact time, temperature, and pH effect. The parameter of initial paracetamol concentrations was studied using a range of 50, 100, and 150 mg L −1 . For a GM3 mass of 80 mg, the adsorbed amount is 14.67 mg g −1 , and the contact time is 180 minutes. This study revealed that composites are efficient for the treatment of landfill leachates.

通过密封复合材料去除水溶液中的扑热息痛

由于垃圾渗滤液的渗入，废物的储存导致水污染和邻近基质的严重问题。不加控制的垃圾填埋场和废物存储会导致地下水污染，从而可能导致严重的健康问题。工程屏障可以解决这些污染问题。这项研究的目的是开发新型复合材料-粘土基，活性炭，水泥和PVA聚合物。这些复合材料旨在用于掩埋垃圾。改变粘土（70％至80％）和活性炭（5％至15％）的含量以获得三种不同的土工材料-GM1，GM2和GM3。在GM3的制备中，所用活性炭的含量高于GM1和GM2，通过吸附测试对乙酰氨基酚的去除能力，实验受到诸如吸附剂质量，初始溶质浓度，接触时间，温度和pH值影响等参数的影响。使用50、100和150 mg L -1的范围研究了扑热息痛的初始浓度参数。对于80mg的GM3质量，吸附量为14.67mg g -1，接触时间为180分钟。这项研究表明，复合材料可有效处理垃圾渗滤液。
