In 2011, the Fukushima Daiichi Nuclear Power Plant accident occurred, and cesium nuclides were released into water environment. This accident causes various severs, including thyroid cancer. Thus, this work synthesized the magnetic-adsorbents (SC200F, SC400F, and SC600F) from waste sugar cane (SC) for removal of cesium ions from water environment. Physicochemical properties such as scanning electron microscope image, specific surface area, and pHpzc were evaluated and cesium ions' adsorption capability was also assessed. Consequently, the specific surface area of prepared SC samples was greater than that of virgin SC. Additionally, the value of point of zero charge (pHpzc) of SC600F (7.5) was higher than that of other adsorbents under our experimental conditions. Next, the amount of cesium ions adsorbed were in the following order: SC (0 mg/g) < SC200F (2.0 mg/g) < SC600F (6.0 mg/g) < SC400F (9.7 mg/g). Moreover, the solid-liquid separation ability of the prepared adsorbent after adsorption was evaluated. The results showed that SC400F was able to be easily separate from the sample solution with the action of the magnetic field under our experimental conditions. Finally, suggested treatment in this study significantly contributes to the development of recycling technology of biomass waste and/or purification of wastewater containing cesium ions.
