Abstract

Nanobentonite particles were used to investigate the elimination of nickel-(II) and copper-(II) at concentrations between 50 and 300 mg L. Batch adsorption tests were conducted to examine the impacts of several factors, including pH, contact time, initial metal ions concentration, adsorbent dose, and temperatures. It was found that the first 20 min of metal ion removal was very fast, and the majority of the reaction was completed. The contact time was 30 min. The optimum pH was found to be 5.0 and 6.0 for copper-(II) and nickel-(II). We carefully evaluated how temperature affected the kinetics and equilibrium of adsorption on nanobentonite particles. The adsorption rate increased as the temperature rose, which is consistent with an exothermic process. The data were subjected to Langmuir, Freundlich, and Dubinin-Radushkevich isotherms at various temperatures. The best explanation for the data was found to be the Langmuir adsorption model. Adsorption kinetics has been investigated using pseudo-first and pseudo-second orders. The data fit best with a pseudo-second-order mechanism. Studies have been done on thermodynamic parameters including Δ°, Δ°, and Δ°. FTIR spectra were used to study the role of functional groups on the surface of nanobentonite in removing heavy metal ions.

摘要

使用纳米膨润土颗粒研究了浓度在50至300 mg/L之间的镍（II）和铜（II）的去除情况。进行了批量吸附试验，以考察几个因素的影响，包括pH值、接触时间、初始金属离子浓度、吸附剂剂量和温度。结果发现，金属离子去除的前20分钟非常迅速，且大部分反应已经完成。接触时间为30分钟。对于铜（II）和镍（II），最佳pH值分别为5.0和6.0。我们仔细评估了温度如何影响纳米膨润土颗粒上吸附的动力学和平衡。吸附速率随温度升高而增加，这与放热过程一致。在不同温度下，对数据进行了Langmuir、Freundlich和Dubinin-Radushkevich等温线分析。发现对数据的最佳解释是Langmuir吸附模型。使用拟一级和拟二级动力学研究了吸附动力学。数据最符合拟二级动力学机制。对包括Δ°、Δ°和Δ°在内的热力学参数进行了研究。利用傅里叶变换红外光谱（FTIR）研究了纳米膨润土表面官能团在去除重金属离子中的作用。
