| Summary: | Adsorption method had been developed by using natural organic adsorbent for the
removal of oil because of its ability to bind the oil molecules into the surface of adsorbent. In
this study, chicken eggshells waste was used and it undergoes irradiation process with four
different amount of dose which was 0.5 kGy, 1.0 kGy, 1.5 kGy, and 2.0 kGy by using Gamma
Cell Irradiator. Three equipment had been used for the characterization process which were the
Scanning Electron Microscope (SEM), Energy Dispersive X-ray spectroscopy (EDX), and
Fourier-Transform Infrared Spectroscopy (FTIR). The adsorption experiment was conducted
to calculate the sorption efficiency by using different mass of samples. The result showed that
irradiated chicken eggshells powder with 2.0 kGy amount of radiation dose has a best
performance as oil adsorbent.
