Magnetic nanoparticles of iron oxide (Fe3O4 NPs) were prepared using a biosynthetic method to investigate their potential use as an adsorbent for adsorption Pb(II) and Cd(II) from the aqueous solution. The present study first time used magnetite leaf extract Portulaca oleracea removal metal ions. Characterizations Fe3O4 NPs (PO-Fe3O4MNPs) achieved by X-ray diffraction (XRD), field emission scan...
One-pot reaction of aldehydes or ketons with aniline derivatives was performed using NaBH4 and Fe3O4 magnetic nanoparticles (MNPs). The optimum amount of Fe3O4 MNPs was 5 mol% under solvent free condition. The corresponding products were obtained in good to excellent yields. The magnetically recoverable iron oxide nanoparticles are found to be efficient for synthesis of amine derivatives. These...
سابقه و هدف: یکی از منابع عظیم آبی قابل استفاده، پساب تصفیه خانه فاضلاب شهری است. استفاده مجدد از این پسآب نیازمند استانداردهایی فراتر از استانداردهای ثانویه میباشد و نیاز است تا آلایندههای آلی و بعضی از ترکیبات مانند نیترات و فسفات موجود در پسآب به میزان بیشتری حذف گردند. در این تحقیق حذف این ترکیبات از پساب ثانویه با استفاده از جاذب نانو ذرات اکسید آهن (مگنتیت) مورد بررسی قرار گرفته است. مو...

Background and purpose: Municipal wastewater treatment plant effluents are amongst the main available water sources. Reuse of these effluents requires further standards beyond secondary standards. Therefore, removal of organic pollutants and some compounds such as nitrate and phosphate from effluents should be done at a greater extent. In this study, removal of these compounds from secondary ef...
