▎ 摘　　要

This research focuses on the batch adsorption efficiency of magnetic adsorbents for removal both for phenol and beta-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 beta-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 beta-naphthol by Fe3O4/PRd and GO-Fe3O4/PRd nanoadsorbents, respectively. Also, thermodynamic studies for both nano-absorbents showed that the absorbing process is an endothermic, spontaneous, and desirable reaction.
