摘要：Due to the amount of yeast residues generated by the industries and their high capacity as biosorbent, this work propos the u of yeast biomass in natura (YB) or modified with ferromagnetic nanoparticles (Fe3O4) (YB-MNP) for Cu(II) removal from water. Synthesized YB-MNP, YB, and magnetite alone (MNP) were characterized by FTIR, XRD, and SEM. It was obrved the efficient impregnation of magnetite on the surface of the biomass. Copper sorption was evaluated in batch tests 再次英语

Langmuir, Freundlich, and Dubinin–Radushkevich (D–R) isotherm models were applied to fit the experimental data. A favorable sorption process was obrved for all the materials, mainly for the D–R model adjusted
