Abstract

Pasir besi alam banyak mengandung fasa partikel Fe3O4 yang memiliki ukuran orde mikron. Melalui metode kopresipitasi kimia menggunakan HCI dan Ammonia sebagai pelarut dan pengendap, telah berhasil disintesis partikel nano Fe3O4 dari pasir besi dengan ukuran partikel ~ 10 nm. Data EDX menunjukkan adanya impuritas dalam sampel hasil sintesis sebagai konsekuensi bahan yang berasal dari alam. Sebagai indikasi keberhasilan, disintesis pula partikel nano Fe3O4 dari bahan dasar kimia (besi (II) dan (III) klorida) melalui metode yang sama. Hasil analisa XRD memperlihatkan kesamaan pola puncak data difraksi dan nilai ukuran kristal yang relatif sama. ====================================================================================================== Iron sand have dominant phase of Fe3O4 which is the particle size still in micron order. Through chemical coprecipitation using HCl and ammonia solution as a solvent and precipitate agent, it was successful to synthesis Fe3O4 nano particles from iron sand with crystal size of ~ 10 nm. EDX data showed that there were impurities as a consequent of natural material. As Successful indication, it was also synthesis Fe3O4 nano particles from chemical solution (iron (II) and (III) chlorides) through the same method. XRD analysis showed that the peak of XRD data of these two samples were similar and have also nearly average crystal size value.
