摘要：
In this study, the date stones/CuFe2O4 nanocomposite was synthesised by a graft of CuFe2O4 nanoparticles on the surface of date stones (DS) for the removal of rhodamine B (RhB) and methyl orange (MO) from aqueous solutions. The adsorption of RhB and MO on DS@CuFe2O4 shows good agreement with second-order kinetic and Langmuir isotherm models. The maximum adsorption capacity was found to be 555.56 03 mg g–1 and 303.03 mg g–1 for RhB and MO, respectively. This adsorption is spontaneous and endothermic. There is excellent regeneration and high reusability of the DS@CuFe2O4 for the RhB and MO removal in six cycles. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
