| چکیده | ||
| در این پژوهش، نانوذرات هسته-پوسته مغناطیسی Fe3O4@SiO2 عامل‌دار شده با شیف باز سالوفن لیگاند سنتز شدند و به‌منظور حذف یون‌های Pb2+ از محلول‌های آبی مورد استفاده قرار گرفتند. در این تحقیق، خصوصیات گروه‌های عاملی سطحی، ساختار کریستالی، خواص مغناطیسی، اندازه و مورفولوژی سطحی این نانوذرات با بکارگیری آنالیزهای تعیین مشخصه FT-IR، XRD، TEM، FE-SEM، EDX و VSM مورد بررسی و شناسایی قرار گرفتند. پس از سنتز شیف باز سالوفن لیگاند ساپورت شده بروی نانوذرات مغناطیسی، مطالعات سینتیکی و تأثیر مقادیر مختلف جاذب به منظور حذف یون‌های سرب دو ظرفیتی از محلول‌های آبی مورد بررسی و مطالعه قرار گرفت. برای این جاذب پیشنهادی مقدار جذب ماکزیمم 91% در دمای محیط محاسبه می گردد که راندمان ایده آلی محسوب می گردد. همچنین قابلیت بازیافت Fe3O4@SiO2-Schiff base به‌منظور حذف Pb2+ برای چرخه‌های متوالی جذب-واجذب مورد بررسی قرار گرفت. نتایج نشان می‌دهد که نانوکامپوزیت سنتزی Fe3O4@SiO2-Schiff base یک جاذب مؤثر، قابل بازیافت با عملکرد عالی برای حذف کادمیوم دوظرفیتی از محلول‌های آبی می‌باشد. | ||

| چکیده [English] | ||
| Here in this research a novel bis-salophen schiff base ligand anchored magnetic Fe3O4@SiO2 nanoparticles was prepared and applied for removal of Pb(II) from aqueous solutions. The obtained adsorbent Fe3O4@SiO2/Schiff base MNPs was characterized by using broad range of characterization techniques including fourier transform infrared (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray analysis (EDX) and vibration sample magnetometry (VSM). After synthesizing bis-salophen schiff base ligand immobilized on Fe3O4@SiO2 nanoparticles, the adsorption activity of this adsorbent for lead ions by nonmagnetic, in terms of effect of adsorbent dosage on the adsorption and kinetics behavior was investigated in detail. Furthermore, the adsorption and regeneration experiment showed there was about 91% in the adsorption capacity of the prepared Fe3O4@SiO2/Schiff base MNPs for lead. Finally, our results suggested that the Fe3O4@SiO2/Schiff base composites have a great potential to be employed for treatment of water and wastewater containing lead(II). | ||
