Abstract

Heavy metals such as arsenic are one of the most important water pollutants and cause many environmental problems. One of the mechanisms for removing arsenic from aqueous media is the adsorption process. In this study, we investigated the efficiency of magnetized multi-walled carbon nanotubes with iron oxide (FeO) nanoparticles. The precipitation method was used to synthesize FeO on PAC-(FeO-f/MWCNTs) functionalized multi-walled carbon nanotubes. The effects of pH, contact time, amount of adsorbent, and contaminant concentration on the adsorption process were examined. Residual arsenic concentration was measured using induction chromatography and inductively coupled plasma mass spectrometry (ICP-MS). The physical and structural characteristics of the adsorbent were analyzed using XRD, TEM, FT-IR, TGA-DTA, BET, FESEM-EDS, Raman spectrum and X-ray. Optimal conditions for arsenic removal were pH = 2, As concentration = 6 mg L, and contact time = 30 minutes, using 0.02 g of adsorbent at room temperature. Also, fitting regression curves to the results showed that the Freundlich model ( > 0.9981) and a pseudo-second-order model ( = 1) best describe the isothermal and kinetic models of the adsorption process, respectively.

摘要

砷等重金属是最重要的水污染物之一，会引发诸多环境问题。从水介质中去除砷的机制之一是吸附过程。在本研究中，我们研究了负载氧化铁（FeO）纳米颗粒的磁化多壁碳纳米管的效率。采用沉淀法在功能化多壁碳纳米管（PAC-(FeO-f/MWCNTs)）上合成FeO。考察了pH值、接触时间、吸附剂用量和污染物浓度对吸附过程的影响。使用感应色谱法和电感耦合等离子体质谱法（ICP-MS）测量残余砷浓度。采用XRD、TEM、FT-IR、TGA-DTA、BET、FESEM-EDS、拉曼光谱和X射线对吸附剂的物理和结构特性进行分析。在室温下，使用0.02 g吸附剂时，去除砷的最佳条件为pH = 2、砷浓度 = 6 mg/L和接触时间 = 30分钟。此外，对结果拟合回归曲线表明，Freundlich模型（> 0.9981）和准二级模型（= 1）分别最能描述吸附过程的等温线和动力学模型。
