Abstract

Penelitian mengenai pengaruh sonikasi terhadap struktur dan  morfologi nanopartikel magnetik yang disintesis dari batuan besi dengan metode kopresipitasi telah dilakukan.  Batuan besi diolah dengan metode kopresipitasi sehingga dihasilkan endapan, kemudian ditambahkan Polietilen Glikol (PEG-4000) dengan perbandingan 1 : 5.  Hasil ini selanjutnya diberi perlakuan tanpa sonikasi dan sonikasi selama 3 dan 4 jam. Dari hasil analisis pola difraksi sinar-X menunjukkan bahwa sampel yang dihasilkan terdiri dari dua struktur yaitu kubik spinel dari magnetit dan heksagonal dari hematit.  Ukuran kristal sampel berkisar antara 41,6 nm – 58,7 nm.  Hal ini membuktikan bahwa sonikasi berpengaruh terhadap struktur dan ukuran nanopartikel magnetik.  Hasil SEM menunjukkan semakin lama waktu sonikasi, ukuran nanopartikel semakin homogen dan penggumpalan semakin berkurang.
