摘要

“老化垃圾”是指倾倒在土地上数年的城市固体废物。选择这种固体废物作为当前研究的吸附剂,因为它在印度泰米尔纳德邦大量可用,并且尚未用于任何其他应用。采用吸附法对废水中的六价铬进行脱除研究。通过BET、TGA、XRD、SEM、FTIR等多种方法对老化垃圾进行分析,确定其表面形貌、官能团、热稳定性、晶体性质和表面积。通过批量吸附实验,验证了接触时间(10 ~ 100 min)、污染物初始浓度(50 ~ 250 mg·L-1)、pH(1 ~ 7)、吸附剂用量(0.5 g·L-1 ~ 3.0 g·L-1)等不同吸附参数对吸附效果的影响。在本研究中,研究人员获得了195.54 mg·g-1的最大吸附量。从动力学结果可以看出,拟一阶模型是最合适的动力学模型。此外,研究结果证实了Langmuir等温线模型是最适合单层吸附过程的等温线模型。本研究表明,在标准优化条件下,老化垃圾具有去除水环境中Cr (VI)的潜力。

Enhanced Adsorptive Removal of Chromium (VI) from Aqueous Solution on Using Aged Refuse: Resource Recovery and Environmental Applications
“Aged refuse” corresponds to municipal solid waste material dumped in land, for several years. This solid waste material is chosen as an adsorbent for the current study since it is available abundantly in the state of Tamil Nadu, India, and has not been used for any other applications. The current study was conducted to get rid of the element chromium (VI) from wastewater by using the adsorption process. The aged refuse was analytically tested through various processes such as BET, TGA, XRD, SEM, and FTIR to determine the surface morphology, functional groups, thermal stability, nature of the crystalline, and surface area. The researchers conducted the batch adsorption study to validate the influence exerted by different sorts of adsorption parameters like contact time (10-100 min), initial concentration of the pollutant (50 mg·L-1 to 250 mg·L-1), pH (1-7), and the dosage of the adsorbent (0.5 g·L-1-3.0 g·L-1). In the current study, the researchers achieved the maximum adsorption capacity of 195.54 mg·g-1. From the kinetic results, it can be understood that the pseudo-first-order model was the most suitable kinetic model. Further, the study outcomes confirm that the Langmuir isotherm model is the best fit by isotherm studies which indicate the monolayer adsorption process. This study indicated that the aged refuse can be potentially used in removing Cr (VI) from water environment under standard optimized conditions.
