Performance of bare magnetite nanoparticles in the adsorption of pentavalent vanadium

In the present study, the separation of vanadium (V) in aqueous medium was studied using an adsorbent of magnetite nanoparticles that was successfully synthesized by co-precipitation method. The synthesized nanoparticles were tested without functionalization to remove vanadium. The maximum adsorption percentage of vanadium by non-functionalized magnetite nanoparticles was ۹۹.۶ percent in optimum conditions: At ambient temperature (۲۰ °C), contact time ۳۰ minutes, ۵۰۰۰ mg/l adsorbent amount, and ۵۰ mg/l initial concentration of vanadium (V).
