Nanopartikel Fe3O4 yang berasal dari pasir besi pantai Glagah Kulon Progo telah berhasil disintesis menggunakan metode kopresipitasi dengan berbagai variasi konsentrasi HCl (10%, 15%, 25% dan 37%). Pengaruh konsentrasi HCl terhadap mikrostruktur dan sifat kemagnetan dari Fe3O4 dilihat dengan menggunakan XRD, SEM EDX serta VSM. Hasil XRD menunjukkan bahwa Fe3O4 yang dihasilkan memiliki struktur kristal kubik invers spinel. Semakin besar konsentrasi HCl, semakin baik derajat kristalinitasnya. Hasil SEM EDX untuk sampel Fe3O4 dengan konsentrasi HCl 37% menunjukkan ukuran butir (grain) yang hampir sama serta tingkat kemurnian sampel Fe3O4 yang dihasilkan sebesar 100% (Fe 72,42% dan O 27,58%). Hasil VSM menunjukkan Fe3O4 hasil sintesis memiliki sifat superparamagnetik serta bersifat soft magnetic. Nanopartikel Fe3O4 dengan konsentrasi HCl 25% memiliki Hc, Mr dan Mmax masing-masing sebesar 0,0215 T, 11,60 emu/gr dan 36,51 emu/gr. Sedangkan Nanopartikel Fe3O4 dengan konsentrasi HCl 37% memiliki Hc dan Mr yang lebih kecil yaitu masing-masing sebesar 0,0017 T dan 10,83 emu/gr serta Mmax yang lebih besar yaitu 36,82 emu/gr.

“…Another study by Prasetrowati et al synthesized Fe3O4 with varying concentrations of NH4OH. VSM testing results showed that sample 2 (15% NH4OH) had a saturation magnetization (Ms) of 25.7 emu/g, remanent magnetization (Mr) of 0.06 emu/g, and coercivity (Hc) of 0.023 T. In contrast, sample 4 (25% NH4OH) had a saturation magnetization (Ms) of 23.6 emu/g, remanent magnetization (Mr) of 2.02 emu/g, and coercivity (Hc) of 0.019 T. Both samples were classified as soft magnetic materials [9].…”

“…The coprecipitation method is the simplest, most economical, and most efficient way to obtain Fe3O4 powder from natural iron sand. The particles produced by this method are relatively stable and highly insoluble in solvents [9], [10], [11] Iron sand contains iron particles like magnetite found along rivers and beaches. These deposits are formed through the processes of weathering, erosion by surface water, and wave action that breaks down the parent rock.…”

This research aims to produce Fe3O4 magnetic nanoparticles-based Taman River sand as the raw material through coprecipitation. The Fe content percentage in the Taman River sand after separation was characterized using XRF testing. The lattice parameters and crystal size of the samples were tested using XRD. The nanoparticles' morphology, structure, particle shape, and elemental content were characterized using SEM-EDX. The magnetic properties and magnetic saturation values were tested using VSM. XRF testing results on the iron sand showed a Fe content of 84.72%. The synthesis resulted in a brNownish-black Fe3O4 nanoparticle powder that a permanent magnet could attract. Based on the XRD results, the Fe3O4 nanoparticle powder peaks were obtained at X-ray diffraction pattern angles of 2θ: 21.44°, 35.38°, 41.74°, 50.78°, 63.36°, 67.70°, and 74.66°, indicating the presence of Fe3O4 nanoparticles. The crystal structure formed was cubic with lattice parameters a = b = c = 8.331 Å and a crystal size of 18.43 nm. SEM-EDX results showed an average particle size of 25-30 nm. VSM results indicated that the Fe3O4 sample had a saturation magnetization (Ms) of 27.36 emu/g, a remanent magnetization (Mr) of -0.01 emu/g, and a coercive field (Hc) of 0.01 T.

Iron sand generally contains minerals such as ilmenite, magnetite, and hematite. Based on the results of previous tests, the main composition of iron sand in Rhee, Sumbawa regency, is magnetite. One method to increase the Fe content in iron sand is by pre-treatment with NaOH. NaOH is also used to precipitate heavy metals in a mineral. In this study, three variations were carried out with the ratio of NaOH: iron sand, namely: 1: 4, 2: 4, and 3: 4 at a temperature of 300 C. Furthermore, the calcination results were followed by the synthesis of Fe3O4 nanoparticles using the coprecipitation method. The results of the XRF characterization showed an increase in Fe levels after being processed by the alkalization treatment. The highest concentration was obtained in 1:4, with a Fe percentage of 91.1%. The results of the XRD characterization showed that the synthesis of Fe3O4 was successfully carried out with single phase Fe3O4 amlording to the data reference 96-9005839 forms and the space group F d -3 m. Crystal size analysis Using the Debey-Scherrer equation, the respective sizes were 12.7 nm, 8.71 nm, and 9.76 nm, respectively.
