“…Selain itu sintesis besi oksida dapat menggunakan limbah besi bubut (Rahmawati et al, 2020), karat besi (Abid et al, 2021, dan red mud (Wang et al, 2020). Metode sintesis yang digunakan untuk mendapatkan senyawa besi oksida yaitu hydrothermal (Hadi et al, 2023), sol-gel (Sundar et al, 2018), microwave-assisted (Panariello et al, 2022), electrospark (Zhuravlev et al, 2019), chemical vapor (Levish et al, 2023), dan kopresipitasi (Mufti et al, 2014). Dari beberapa metode sintesis senyawa besi oksida, metode kopresipitasi merupakan metode sintesis kimia yang secara luas telah digunakan untuk menghasilkan nanopartikel oksida besi (Samrot et al, 2021).…”

Senyawa besi oksida pada batuan vulkanik Pulau Ambon memiliki potensi untuk dimanfaatkan sebagai material maju di masa depan. Penelitian ini bertujuan untuk mengekstraksi senyawa besi oksida pada batuan vulkanik Pulau Ambon menggunakan metode kopresipitasi. Hasil penelitian menunjukkan senyawa besi oksida yang dihasilkan memiliki kemurnian dibawah 50%. Hal ini dikarenakan masih adanya beberapa senyawa oksida yang terdeteksi oleh instrumen X-Ray Fluorescence (XRF). Fasa mineral oksida yang terdeteksi oleh instrumen X-Ray Diffraction (XRD) adalah magnetit (Fe3O4), maghemit (𝛾-Fe2O3), dan hematit (𝛼-Fe2O3). Ukuran kristal dari hasil perhitungan persamaan Scherrer menghasilkan nilai rata-rata sebesar 13,732 nm. Dari hasil pengamatan Scanning Electron Microscope (SEM) menunjukkan adanya aglomerasi dengan bentuk permukaan yang bulat. Ukuran partikel yang dianalisis dari gambar SEM menggunakan software ImageJ menghasilkan nilai rata-rata sebesar 729,184 nm. Hasil ini menunjukkan metode kopresipitasi telah berhasil mempelajari senyawa besi oksida dari batuan vulkanik Pulau Ambon. Kedepannya senyawa besi oksida dari hasil ekstraksi dapat diaplikasikan sebagai material fotokatalis dan antimikroba.

“…MW-assisted magnetic nanoparticle synthesis − is an alternative to conventional coprecipitation, sol–gel, hydrothermal, ionothermal, thermal decomposition, and microemulsion templating synthesis techniques, due to its reduced energy consumption and time efficiency. Some common challenges in magnetic nanoparticle synthesis are the dispersity in size, phase, and coagulation .…”

Achieving colloidal and chemical stability in ferrofluids by surface modification requires multiple steps, including purification, ex situ modification steps, and operation at high temperatures. In this study, a single-step microwave-assisted methodology is developed for iron oxide nanoparticle (IONP) synthesis utilizing a series of imidazolium-based ionic liquids (ILs) with chloride, bis(trifluoromethylsulfonyl)imide, and pyrrolide anions as the reaction media, thus eliminating the use of volatile organics while enabling rapid synthesis at 80 °C as well as in situ surface functionalization. The characterized surface functionality, hydrodynamic particle size, magnetization, and colloidal stability of the IONPs demonstrate a strong dependence on the IL structure, ion coordination strength, reactivity, and hydrophilicity. The IONPs present primarily a magnetite (Fe 3 O 4 ) phase with superparamagnetism with the highest saturation magnetization at 81 and 73 emu/g at 10 and 300 K, respectively. Depending on the IL coating, magnetization and exchange anisotropy decrease by 20 and 2−3 emu/g (at 35 wt % IL), respectively, but still represent the highest magnetization achieved for coated IONPs by a coprecipitation method. Further, the surface-functionalized superparamagnetic magnetite nanoparticles show good dispersibility and colloidal stability in water and dimethyl sulfoxide at 0.1 mg/mL concentration over the examined 3 month period. This study reports on the intermolecular and chemical interactions between the particle surface and the ILs under synthetic conditions as they relate to the magnetic and thermal properties of the resulting IONPs that are well suited for a variety of applications, including separation and catalysis.
