Abstract
The radiolytic reduction method has been used in the synthesis of magnetite, which applied solvated electrons (e,−) as a reductor. The aqueous solution containing iron chloride salt and iso-propanol as scavenger agents were irradiated in the gamma-irradiated chamber at Gamma Irradiator Laboratorium Dr. Mirzan T. Razzak, M.Eng., STTN-BATAN, Indonesia. The purpose of this research is to study the formation of Fe3O4 particles via radiolytic reduction by varying the irradiation dose (25, 50, 75, and 100 kGy). The analysis result using X-Ray Diffractometer (XRD) shows the Fe3O4 phases were formed since irradiation dose 25 kGy. As the irradiation dose increase caused the increasing of saturation magnetization of Fe3O4 with Ms value 5.24; 8.00; 14.2; 21.1emu/g for irradiation dose 25, 50, 75, 100 kGy respectively. Particle size analysis of Fe3O4 that irradiated at 100 kGy has an average size of 331 nm. Functional group identification was confirmed using Fourier Transform Infra-Red (FTIR) Spectrophotometer to show the formation of Fe-O bonds. Based on the characterization results, the radiolytic reduction method has been successfully used in the synthesize of Fe3O4 since radiation dose 25 kGy.
