The Fe (OH)₂ nanoparticles were obtained by slow addition of sodium hydroxide solution to eucalyptus extract. Then, to obtain α-Fe₂O₃, calcination of Fe (OH)₂nanoparticles was carried out at 550 °C. These oxides and nanocomposites were diagnosed by FTIR, XRD, FESEM, and DLS techniques. Brunauer-Emmett-Teller (BET) was used to determine the surface area of ​​the nanomaterials. X-ray diffraction (XRD) examination showed that the size of α-Fe₂O₃ nanoparticles was 48 nm, characterized using several techniques, including XRD, AFM, FT-IR, and FESEM. These nanocomposites were used to study the adsorption of methyl orange dye from their aqueous solutions. The effects of equilibrium time, surface area weight, and temperature on the adsorption process were investigated. The results showed that the optimal equilibrium time was 40 min for the α-Fe2O3/paraffine nanocomposite and 60 min for the Fe2O3/AC nanocomposite. The optimal weight for dye removal was 0.25 g for the α -Fe2O3/paraffine nanocomposite. The optimal pH for removing methyl orange dye was 5 for all nano composites.</p> Batool Sarhan Mansoor Abdulqadier Hussien Al Khazraji Copyright (c) 2026 International journal of health sciences http://creativecommons.org/licenses/by-nc-nd/4.0 2026-05-03 2026-05-03 10 2 88 98 10.53730/ijhs.v10n2.15930
