Abstract

Sintesis nanopartikel Fe3O4 menggunakan templet PEG dengan metode kopresipitasi telah dilakukan.  Perbandingan serbuk besi dengan templet PEG adalah 1:1.  Jenis PEG yang digunakan adalah PEG-1000, PEG-2000, PEG-4000, dan PEG-6000.   Penelitian ini bertujuan untuk melihat pengaruh berat molekul PEG terhadap ukuran kristal, ukuran partikel, dan morfologi permukaan nanopartikel Fe3O4.  Ukuran kristal diperoleh dengan menggunakan metode difraksi sinar-X (XRD) dan ukuran partikel serta morfologi permukaan nanopartikel  Fe3O4 diperoleh dengan menggunakan alat Scanning Electron Microscopy (SEM).  Dari analisis hasil difraksi sinar-X didapatkan ukuran kristal nanopartikel Fe3O4 berturut-turut adalah 19,32 nm, 19,37 nm, 21,35 nm dan 18,29 nm. Berdasarkan hasil SEM terlihat bahwa nanopartikel Fe3O4  berbentuk spherical (bulat) dengan ukuran partikel berturut-turut 85 nm, 67,75 nm, 86,5 nm, dan 60,75 nm.
