Penghasilan zarah nano ferum oksida (FeNPs) daripada garam ferosenium menggunakan hidrogel poli-akril amida (P(Am) sebagai templat

Abstract

The aim of this study was to investigate the feasibility of hydrogel to produce ferum oxide nanoparticles (FeNps). The polyacrylamide (PAAm) hydrogel was synthesized by using free radical polymerization method. The hydrogel water uptake ability has been conducted and the highest swelling ratio was occured at pH10 basic buffer solution. Hydrogel was characterized by using scanning electron microscopy (SEM) followed by energy dispersive X-ray spectroscopy (SEM-EDEX) to determine the iron (Fe) percentage. After calcination process, nanoparticles were extracted from the PAAm hydrogel and further analysed using transmission electron microscopy (TEM) and X-ray diffraction analysis (XRD). TEM results showed that the particles diameter was in ranged of 5 - 20 nm. XRD examination confirmed the existance of ferum oxide particles (Fe2O3). The result demonstrates the feasibility of using hydrogel as a promising nanoreactor. Show more
