چکیده مقاله
Heavy metals HMs removal from wastewater is one of the main bottleneck of wastewater treatment WWT process In this study, we synthesized a novel adsorbent by integrating Fe۳O۴ magnetic nanoparticle NPs and dried microalgae biomass as natural adsorbent, named Fe۳O۴@micrpalge to efficiently adsorb lead Pb from polluted WW The performance of Fe۳O۴@micrpalge was compared with microalgae alone to identify the effect of NPs Moreover, the impact of operational parameters including Fe۳O۴@micrpalge dosage, contact time, Pb initial concentration and pH on adsorption performance were investigated According to the results, microalgae dried biomass without NP could only remove ۷۲% of Pb under the optimal conditions While, the maximum Pb removal efficiencies of ۸۴% was obtained for Pb, under the optimal conditions of Fe۳O۴@micrpalge dosage: ۲۰ mg, HMs initial concentrations: ۱۰۰ mg/L, pH: ۱۱ and contact time ۶۰ min The adsorption kinetic and isotherm followed the pseudo first order and Freundlich, respectively indicating that both chemisorption and physisorption were involved in Pb adsorption process of Fe۳O۴@micrpalge Our finding suggest a sustainable and promising approach for efficient removal of HMs from contaminated wastewater
