“…Also, one of the most important pollutants in water is the excess of nutrients (nitrogen and phosphorus) that threatens human health and the environment. In particular, high amount of phosphorus promotes algae growth in water, since it is usually regulated by microorganisms, which in its turn decreases oxygen concentration and leads to eutrophication (extraordinary growth of algae as a result of excess nutrients in water bodies) on rivers, lakes, and seas worldwide [5,6]. Due to phosphorus is a non-renewable element and huge amount of phosphorus is lost annually for lack of phosphorus recovery, its recycling is of great interest especially with increasing demands, such as in the agriculture [7] as a fertilizer [8,9] or industrial usages as ingredients for human food, pharmaceuticals, detergents, and food additive in the animal feed [10,11].…”

Highlights• Immobilization of magnetite nanoparticles on cationic polymer was synthesized.• Phosphate removal using magnetite based nanocomposites was tested.• Adsorption isotherms of phosphate at two pH; 5 and 7 were performed.• Different isotherms models were applied for experimental data fitting.• Regeneration and reusability of the magnetite based nanocomposites were carried out. Graphical Abstract 2 AbstractA novel nanocomposite based on magnetite nanoparticles (Fe3O4-NPs) immobilized on the surface of the cationic exchange polymer, C100, using a modification of the coprecipitation method was developed to obtain magnetic nanocomposites (NCs) for phosphate removal and recovery from water. High resolution TEM-EDS, SEM, XRD, and ICP-OES were used to characterize the NCs. The continuous adsorption process by the so-called breakthrough curves was used to determine the adsorption capacity of the Fe3O4 based NC. The adsorption 3 capacity conditions were studied under different conditions (pH, phosphate concentration and concentration of NPs). The optimum concentration of iron in the NC for phosphate removal was 23.59 mgFe/gNC. The sorption isotherms of this material were performed at pHs 5 and 7.Taking into account the real application of this novel material in real water, the experiments were performed at pH 7, achieving an adsorption capacity higher than 4.9 mgPO4-P/gNC.Moreover, Freundlich, Langmuir and a combination of them fit the experimental data and were used for interpreting the influence of pH on the sorption and the adsorption mechanism for this novel material. Furthermore, regeneration and reusability of the nanocomposite were tested obtaining 97.5 % recovery of phosphate for the first cycle and at least 7 cycles of adsorptiondesorption were carried out with more than 40% of recovery. Thus, this work described a novel magnetic nanoadsorbent with promoting properties for phosphate recovery in wastewater.

“…and Peng, 2008). However, this does not meet the United States Environment Protection Agency criterion for acceptable phosphorus concentration in water (less than 0.1 mg/L) (Trepanier et al, 2002). Thus, the secondary effluent of sewage treatment plants should be treated further via a suitable purification technology.…”
