For the first time in this study, sustainable magnetic alginate composite beads were designed containing citric acid-modified sawdust (CA-sawdust) as bio-waste and Fe3O4 nanoparticles. This novel eco-friendly composite (Alginate/CA-sawdust/Fe3O4 beads) was successfully applied to remove malachite green (MG). Easy separation under a magnetic field and reusability could be mentioned as two noteworthy properties of this bio-sorbent. This process was described well with Langmuir isotherm and pseudo-first-order kinetic models. Moreover, both film and intraparticle diffusion models were probable in the MG removal mechanism.
