This work shows that magnetic adsorbents with different porosity characteristics can be produced by carbonization and steam activation of a mixture of a furfuryl alcohol and iron-containing compound, such as ferrocene (PFA/ferrocene), FeCl₃ (PFA/FeCl₃) and FeSO₄ (PFA/FeSO₄). The materials obtained in this work possess magnetic properties that are revealed in the neodymium magnet balance test as an increase in weight loss with an increase in iron content in the material. In order to verify whether the magnetic properties facilitate the removal of the used adsorbent, the sedimentation test was carried out. The porous texture characteristics obtained from the N₂ adsorption isotherms at 77 K show a huge differences in porosities depending on the type of iron compound used. The presence of ferrocene promotes the formation of mesoporosity, whereas the presence of iron(II) sulphate induces microporosity. XRD measurements reveal the presence of magnetite and hematite in all magnetic adsorbents. The intensity of the XRD peak designated to magnetite increases with an increase in the saturation magnetization. Adsorption of Congo red (CR), phenol (P), atrazine (A) and isoproturon (I) from aqueous solutions was carried out at a temperature of 24 °C in a static system. The magnetic properties accelerated the sedimentation processes and materials demonstrated a high adsorption ability toward organic contamination. The adsorption capacity on PFA-based MAC is strongly related to adsorbent porosity.

这项工作表明，通过糠醇和含铁化合物（例如二茂铁（PFA/二茂铁）、FeCl 3 (PFA/FeCl 3 ) 和 FeSO）的混合物的碳化和蒸汽活化，可以生产具有不同孔隙率特性_的磁性_吸附剂。₄（PFA/FeSO ₄）。这项工作中获得的材料具有磁性，在钕磁铁天平测试中显示，随着材料中铁含量的增加，重量损失增加。为了验证磁性是否有利于所用吸附剂的去除，进行了沉降试验。_{从 77 K 的 N 2}吸附等温线获得的多孔结构特征显示，根据所使用的铁化合物的类型，孔隙率存在巨大差异。二茂铁的存在促进中孔的形成，而硫酸亚铁(II)的存在则引发微孔。XRD 测量表明所有磁性吸附剂中都存在磁铁矿和赤铁矿。指定为磁铁矿的 XRD 峰的强度随着饱和磁化强度的增加而增加。在静态系统中，在 24 °C 的温度下从水溶液中吸附刚果红 (CR)、苯酚 (P)、莠去津 (A) 和异丙隆 (I)。磁性加速了沉降过程，材料表现出对有机污染物的高吸附能力。基于 PFA 的 MAC 的吸附容量与吸附剂孔隙率密切相关。
