The presence of dyes in water bodies has become a significant concern in recent years. In this study, a magnetic nanocomposite synthesized from activated carbon (AC) and FeO nanoparticles (AC/FeO) was employed as an adsorbent to remove janus green (JG) and safranin-O (SO) dyes. The AC/FeO nanocomposite had particle sizes smaller than 100 nm. The specific surface area, pore size, and pore volume average of the AC/FeO nanocomposite were 329.56 m g, 3.67 nm, and 0.289 cm g, respectively. The pH of AC/FeO magnetic nanocomposite was found to be 5.3. Optimal conditions for removal were determined to be a dye concentration of 20 mg L, a sonication time of 18 min, a nanocomposite dosage of 0.023 g, and a pH of 7. The AC/FeO nanocomposite exhibited excellent adsorption performance, achieving removal efficiencies of 95.79% and 97.60% for JG and SO, respectively. Moreover, the magnetic nanocomposite demonstrated good reusability, making it a promising candidate for removing JG and SO dyes from aqueous solutions. The AC/FeO nanocomposite was used to remove JG and SO from different environmental water samples, and the removal efficiency was obtained in the range of 87.65-94.81%. Overall, this study highlights the potential of the AC/FeO magnetic adsorbent, as an effective adsorbent for removing JG and SO dyes from water, which could have significant implications for water treatment and environmental protection.
近年来，水体中染料的存在已成为一个重大问题。在本研究中，由活性炭（AC）和FeO纳米颗粒合成的磁性纳米复合材料（AC/FeO）被用作吸附剂，以去除姬姆萨绿（JG）和番红O（SO）染料。AC/FeO纳米复合材料的粒径小于100nm。AC/FeO纳米复合材料的比表面积、孔径和平均孔体积分别为329.56 m²/g、3.67nm和0.289 cm³/g。发现AC/FeO磁性纳米复合材料的pH值为5.3。确定去除的最佳条件为染料浓度20mg/L、超声处理时间18分钟、纳米复合材料用量0.023g和pH值7。AC/FeO纳米复合材料表现出优异的吸附性能，对JG和SO的去除效率分别达到95.79%和97.60%。此外，磁性纳米复合材料表现出良好的可重复使用性，使其成为从水溶液中去除JG和SO染料的有前途的候选材料。AC/FeO纳米复合材料用于去除不同环境水样中的JG和SO，去除效率在87.65-94.81%范围内。总体而言，本研究突出了AC/FeO磁性吸附剂作为从水中去除JG和SO染料的有效吸附剂的潜力，这可能对水处理和环境保护具有重要意义。
