Novel composite magnetic nanoparticles (CuFe 2 O 4 ) were synthesized from industrial sludge by acid leaching, chemical exchange, and ferrite processes in the laboratory. For the first time, these products were applied to investigate the Sr adsorption kinetics and the related thermodynamics in seawater. Rapidly enhanced Sr adsorption was observed when the solution pH changed from 2.61 to 10.25. The maximum adsorption capacity was 23.04 mg·g −1 at 318 K (pH 10.25). Sr adsorption decreased with the increase of the ionic strength from 0.01 to 0.5 mol·L −1 at pH 2.61-pH 10.25, indicating that the outer-sphere mechanism was involved in the Sr adsorption at the pH interval. This reaction is spontaneous and endothermic, as indicated by the negative change in the standard free energy (∆G • = −5.68, −6.45, and −7.23 kJ·mol −1 at 298, 308, and 318 K, respectively) and positive ∆H • value (2.11 kJ·mol −1 ). The positive ∆S • (9.38 mol −1 ·K −1 ) further confirms that the randomness increased at the solid-solution interface during adsorption. These new results indicate that the composite magnetic nanoparticles can be used for the removal of radiogenic 90 Sr nuclide in seawater that was released after the 3/11 earthquake offshore of Japan.

“…Different nanoscale ferrites have been tested for the removal of metals such as arsenic [55], chromium [56] and cadmium [57]. Liang et al synthesized a series of Mnsubstituted magnetites and investigated the effect of Mn substitution on the reactivity of magnetite regarding to the Pb 2+ adsorption capability.…”

Nanosized magnetite has emerged as an adsorbent of pollutants in water remediation. Nanoadsorbents include magnetic iron oxide and its modifiers/ stabilizers, such as carbon, silica, clay, organic moieties (polymers, aminoacids, and fatty acids) and other inorganic oxides. This review is focused on the recent developments on the synthesis and use of magnetic nanoparticles and nanocomposites in the treatment of contaminated water. The emphasis is on the influence of the iron oxide modifiers on some properties of interest such as size, BET area, and magnetization. The characteristics of these nanomaterials are related to their ability to eliminate heavy metal ions and dyes from wastewater. Comparative analysis of the actual literature was performed aiming to present the magnetic material, its preparation methodology and performance in the elimination of the selected pollutants. Vast information has been properly summarized according to the materials, their properties and preferential affinity for selected contaminants. The mechanisms governing nanomaterial's formation as well as the interactions with heavy metals and dyes have been carefully analyzed and associated to their efficiency.
