Synthesis of a novel nanocomposite based on date stones/CuFe₂O₄ nanoparticles for eliminating cationic and anionic dyes from aqueous solution

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