This research focuses on the batch adsorption efficiency of magnetic adsorbents for removal both for phenol and β-naphthol from aqueous solution. Two kinds of nano-adsorbents were investigated: magnetic/polyrhodanine (Fe₃O₄/PRd) and graphene oxide-magnetic/polyrhodanine (GO-Fe₃O₄/PRd). GO can improve to be the best nano-adsorbent for phenol and β-naphthol removal due to its large specific surface areas with a maximum adsorption capacity of 191.0 and 226.2 mg g⁻¹, respectively, at contact time 15 min. The characterization of prepared nano-adsorbents by XRD, FESEM, FTIR, VSM, EDS, and BET analysis. The kinetic models indicated that the adsorption process followed a Pseudo-Second-Order model, and the Freundlich and Langmuir isotherm models described the adsorption behavior of phenol and β-naphthol by Fe₃O₄/PRd and GO-Fe₃O₄/PRd nano-adsorbents, respectively. Also, thermodynamic studies for both nano-absorbents showed that the absorbing process is an endothermic, spontaneous, and desirable reaction.

这项研究的重点是磁性吸附剂对水溶液中苯酚和β-萘酚的去除效率。研究了两种纳米吸附剂：磁性/聚罗丹宁（Fe ₃ O ₄ / PRd）和氧化石墨烯-磁性/聚罗丹宁（GO-Fe ₃ O ₄ / PRd）。GO的比表面积大，最大吸附容量为191.0和226.2 mg g ^-1，可提高其成为去除苯酚和β-萘酚的最佳纳米吸附剂。，分别在15分钟的联系时间。通过XRD，FESEM，FTIR，VSM，EDS和BET分析对制备的纳米吸附剂进行表征。动力学模型表明吸附过程遵循伪二阶模型，Freundlich和Langmuir等温模型描述了Fe ₃ O ₄ / PRd和GO-Fe ₃ O ₄ / PRd对苯酚和β-萘酚的吸附行为。纳米吸附剂。同样，对两种纳米吸收剂的热力学研究表明，吸收过程是吸热的，自发的和理想的反应。
