Effect of Fe3O4 in enhancement optical and gamma ray absorption properties of geopolymer apron cassava starch/black carbon/glycerin

摘要: Abstract Geopolymer apron cassava starch/BC/Fe3O4/glycerin has been synthesized for various amount of Fe3O4 (0.5%, 1%, and 1.5%) into starch black carbon (BC) solutions. The quantitative analysis from Fourier transforms infra-red (FTIR) was used to determine the optical properties, dielectric function, energy loss attenuation constant, propagation constant. higher value distance between two ((LO-TO)) phonon vibration, constant strong correlation with absorption properties mechanical properties. effectiveness radiation shielding also density, linear coefficient (μ), mass (μs), half layer (HVL), mean free path (MFP) gamma source IBT 103 Cs 137. 0.178 cm − 1 , sample density 0.984 g/ 3 HVL 3.893 cm, MPF 5.618 cm. best characteristic in supporting composite performance as an applications are 1.5% composite. This study shows that FTIR spectra could be useful determining starch/BC/Fe3O4/glycerin.
