In this research, spinel ferrite (CuFe2O4) magnetic nanoparticles were synthesized by the solvothermal approach in the polyol media and used for the adsorptive removal of Reactive Red 141 (RR 141) as a model of organic dye. Batch adsorption studies were carried out for various pH values, nanoadsorbent loadings, contact times, temperatures, and initial concentrations of the organic pollutant. The adsorption isotherms were in the range of 10–50 ppm and the results fitted well with Langmuir isotherm. The sorption kinetic studies well-defined to Ho’s pseudo-second order model. This research suggests an effective low cost CuFe2O4 nanoadsorbent with a reasonably high efficiency for the removal of RR141 compound, which allows convenient recovery from aqueous media using a weak external magnetic field.
