A polypyrrole–chitosan–Fe₃O₄ magnetic nanocomposite (PPy–CS–Fe₃O₄ MNC) was prepared by in situ coprecipitation of iron salts in the presence of chitosan followed by chemical oxidative polymerization of pyrrole on the magnetic chitosan. Afterward, the nanocomposite was applied as a magnetic nanosorbent for the removal of carbamazepine (CBZ) from the wastewater samples. The prepared adsorbent was characterized by various modern surface and microstructure analyzing methods. Several operating parameters affecting the removal efficiency of the CBZ including sample pH, amount of sorbent, initial concentration and adsorption time were investigated and adjusted. However, under the optimal conditions, the PPy–CS–Fe₃O₄ MNCs showed prominent removal performance compared to the bare Fe₃O₄ magnetic nanoparticles. According to the results, the PPy–CS–Fe₃O₄ MNCs could eliminate the CBZ from water medium with an efficiency of 94.5%. in the 25 min. In contrast, it took about an hour to remove 65% of the CBZ using bare Fe₃O₄ magnetic nanoparticles. The experimental results revealed that the CBZ sorption on the PPy–CS–Fe₃O₄ MNCs was fitted well with the pseudo-second-order kinetic model (R² = 0.9901). Moreover, the adsorption model was in accordance with the Langmuir isotherm with the adsorption capacity of 121.95 mg g^-1. It was found that PPy–CS–Fe₃O₄ MNCs could be frequently applied for CBZ removal up to five times without noticeable decrease in its adsorption efficiency. The adsorption results established the high potential of synthesized MNCs as a robust and promising adsorbent for water treatment.

聚吡咯-壳聚糖-Fe ₃ O ₄磁性纳米复合材料（PPy-CS-Fe ₃ O ₄ MNC）是通过在壳聚糖存在下原位共沉淀铁盐，然后在磁性壳聚糖上进行吡咯的化学氧化聚合而制得的。然后，将纳米复合材料用作磁性纳米吸附剂，用于从废水样品中去除卡马西平（CBZ）。通过各种现代的表面和微观结构分析方法对制备的吸附剂进行了表征。研究和调整了影响CBZ去除效率的几个操作参数，包括样品的pH值，吸附剂的量，初始浓度和吸附时间。但是，在最佳条件下，PPy–CS–Fe ₃ O与裸露的Fe ₃ O ₄磁性纳米粒子相比，有_4个MNC显示出显着的去除性能。根据结果​​，PPy–CS–Fe ₃ O ₄跨国公司可以从水介质中消除CBZ，效率为94.5％。在25 分钟内 相比之下，使用裸露的Fe ₃ O ₄磁性纳米颗粒去除了65％的CBZ大约需要一个小时。实验结果表明，PPy–CS–Fe ₃ O ₄跨国公司对CBZ的吸附与拟二级动力学模型（R ²= 0.9901）。此外，吸附模型符合Langmuir等温线，吸附容量为121.95  mg  g ^-1。结果发现，PPy–CS–Fe ₃ O ₄跨国公司在去除CBZ方面可频繁使用多达五次，而其吸附效率却没有明显下降。吸附结果证明了合成的跨国公司作为水处理的强大而有前途的吸附剂具有很高的潜力。
