Analisis Gugus Fungsi, Morfologi dan Ukuran Partikel Manganese Ferrite yang Disintesis dari Pasir Besi
Abstract
Manganese ferrite (Mn ferrite) telah berhasil disintesis dengan metode kopresipitasi pada suhu 60 ℃. Mn ferrite disintesis dari pasir besi sebagai prekusornya. Tujuan dari penelitian ini untuk mensintesis Mn ferrite dari pasir besi dan menganalisis gugus fungsi serta morfologinya. Sampel dibuat dengan memvariasikan NaOH yaitu 3 M, 6 M dan 9 M. Struktur kristal, gugus fungsi dan morfologi dikarakterisasi dengan X-ray Difractometer (XRD), Fourier Transform Infra Red (FTIR), dan Transmission Electron Microscopy (TEM). Hasil spektra FTIR mengkonfirmasi adanya gugus fungsi metal-oxide (M-O) pada kisi tetrahedral dan oktahedral pada bilangan gelombang masing-masing 462 cm-1 dan 578 cm-1. Hal ini diidetifikasi sebagai gugus Mn-O dan Fe-O sekaligus mengkonfirmasi pembentukan struktur spinel. Pengamatan morfologi menunjukkan bahwa sampel terlihat mengalami aglomerasi karena adanya interaksi magnetik. Hasil pengamatan ukuran partikel berada pada kisaran 30 – 50 nm yang diukur menggunakan software Image-J. Ukuran butir terlihat lebih besar dibandingkan hasil perhitungan ukuran kristalit berdasarkan data XRD karena sampel mengalami aglomerasi sehingga beberapa butir menggumpal menjadi satu dan terlihat seperti satu partikel.
Kata kunci: Mn-ferrite, gugus fungsi, morfologi, ukuran partikel
