“…parameter value of 8.355 Å, 6.796 Å, and 8.368 Å, respectively. In[11] study, the lattice parameter value of coprecipitated iron sand-based Copper Ferrite was 8.37 Å.As shown in Figure3, sample 1:2 exhibited the lowest lattice parameter (6.796 Å) among other variations, which may be attributed to the high amount of atomic FE. Sample 2:1 has the highest…”

“…The average crystal size of the CuFe 2 O 4 nanoparticle with concentration variation of 1:1, 1:2, and 2:1 was 22.330 nm, 26.656 nm, and 22.133 nm, respectively. The crystal size of iron sand-based copper ferrite with coprecipitation ranges between 23 and 90 nm[11].As shown in Figure2, the sample variation of 2:1 has the smallest crystal size (22.33 nm), which may be attributed to the amount of atomic Cu in the sample. On the other hand, sample 1:2 has the largest crystal size (26.656 Å) among other sample variations due to the high amount of Fe.…”

This study aimed to synthesize iron sand-based Copper Ferrite (CuFe2O4) using the coprecipitation method. The iron sand was taken from South Cianjur and used as a Fe cation source to synthesize CuFe2O4 nanoparticles. Three composition variations of CuCl2.6H2O and iron sand (Fe3O4) were employed, i.e., 1:1, 1:2, and 2:1. Samples were characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy - Energy Dispersive X-Ray (SEM-EDX), and Atomic Adsorption Spectroscopy (AAS). The XRD analysis exhibits three synthesis-phase results: CuFe2O4, Fe2O3, and CuO. The produced CuFe2O4 has two crystal structures: t-CuFe2O4 in 1:2 variation and c-CuFe2O4 in variations 1:1 and 2:1. Adding Cu resulted in smaller crystal size and higher lattice parameters. SEM-EDX analysis of 1:2 sample variation showed a round-shaped particle of 102.57 nm. AAS analysis showed that the increased mole of Cu decreases the heavy metal, including Pb and Mn, adsorption capacity. The largest adsorption capacity was found in the 1:2 (60.698 mg/g).

“…Spinel ferit dapat diaplikasikan pada biomedis, perangkat elektronik (Anandan et al, 2017), Magnetic Resonance Imaging (MRI) dengan sifat magnet spinel ferit MFe2O4 (M = Fe, Co, Mn) untuk membantu identifikasi penyakit (C.P et al, 2012), dan penyerap gelombang mikro (Sembiring, et al, 2019). Ferit dengan rumus X.Fe2O3 (X= MgO, ZnO, MnO dan CaO) dapat dibuat dalam beberapa metode seperti mechanical alloying, penambahan MgO pada Fe2O3 metode co-presipitasi (Saputra et al, 2020), metode hydrothermal dan sebagainya. ZnO merupakan komponen material elektrik karena memiliki sifat mesoporous, sebaran area yang besar, resisitivitas yang rendah, sifat magnetik, sifat listrik dan sifat optik yang menarik (Sarkar et al, 2012).…”

This research is based on the abundance of natural materials such as manganese and iron ore. Manganese is usually used for metal coating and has durability so that it is rich in properties to be used for various purposes in the chemical, pharmaceutical, and technological industries. Meanwhile, iron ore is a stable type of oxide so that it has strong properties and is not easily corroded. This research is a type of experimental research conducted at the Laboratory of Material Physics and Biophysics Faculty of Mathematics and Natural Sciences (FMIPA), Padang State University (UNP), and the Chemistry Laboratory of FMIPA UNP. The tools used are HEM-3D, XRD, and UV-VIS. The precursors were prepared by varying the composition of the ratio of MnO-Fe₂O₃ and PS respectively 0,2:0,2:1 ; 0,4:0,4:1 ; 0,6:0,6:1 ; 0,8:0,8:1 ; 1:1:1. This coating is made by means of the spin coating method and uses a temperature of 60 ° using a oven. The results of this study are the maximum crystal size obtained in MnO is 61.26 nm, Fe₂O₃ is 50.45 nm, and MnO-Fe₂O₃ is 53.08 nm. Also, the maximum% degradation produced is 65.97% in a methyl orange solution, this shows that the MnO-Fe₂O₃/PS layer is well degraded. This degradation ability is known as self cleaning because it is able to break down dirt.
