Green synthesized superparamagnetic iron oxide nanoparticles for water treatment with alternative recyclability

• Simple and ecofriendly green synthesis of functionalized superparamagnetic iron oxide nanoparticles. Nanoparticles absorbed the model dyes above 80% efficiency for a wide range conditions 94% optimum conditions. We present successful recyclability by growing nanoparticles on surface polyvinyl alcohol solid support. Widely used water treatment methods are based chemicals that leave residual unwanted impurities, instigating long-term health impacts. Hence, m agnetic n ano p articles (MNPs) have been to fill those gabs commonly metallic adsorption in contaminated waters. High volume ratio MNPs allows larger capacity pollutant adsorption. In this study, synthesized novel approach using plant phytochemicals with capability absorbing multiple organic pollutants. Herein, we studied crude extracts simple maceration technique. The reaction was supported further heat treatments at supercritical condition ethanol complete reduction process Our XRD result shows formation spherical cubic goethite (before treatment-Y0PL), magnetite (after -Y0PR) functionalization-Y0PRP) an average crystalline size 277, 29, 45 nm respectively. Phytochemicals increased altered texture magnetic properties were measured magnetization dependence external field show behavior Ms = 44 (Hc 123 Oe), 36 133 Oe) 13 emu/g Y0PR, Y0PRP Y0PL, Absorption/reduction against MB (10–140 mg/L) 4-NA (0.5–1 mM). As under very short time Moreover, work introduces alternative particular weakly them Therefore, prepared study easy synthesize cost-effective enviro-friendly agents.
