Modifikasi Nanopartikel Magnetite Menggunakan Karbon Aktif Untuk Adsorbsi Log…

Natural sand of west coast of Sumatera Island consists of magnetic phase such as magnetite (Fe3O4), hematite (α-Fe2O3), maghemite (γ-Fe2O3) phases or other phase namely ilminate (FeTiO3). When the particles size of these particles especially magnetic particles reduces ti nano size, then these particles posses a unique property called superparamagnetic. Due to this property, this particle …
