| Recently, the nuclear accident of Fukushima in Japan has caused many radioactive materials to leak into the sea and the interest in the disposal of radioactive pollutants in the world is getting bigger. Thus, effective treatment techniques for removing radioactive ions in water are needed. In this study, chitin was used to remove Cs(I) in water. Chitin, hexacyanoferrate and CuCl2 were synthesized and adsorbent (CuHCF) was prepared and used for characterization and batch experiments. SEM / EDX and XRD analysis confirmed the K, Fe and Cu synthesis of CuHCF. Batch experiments were performed by pH, time, and initial concentration. The removal of CuHCF was 1.5 times higher than chitin. As a result of the time experiment, all of the three adsorbents reached equilibrium after 300 minutes and the optimum time was set to 300 minutes. As a result of the isothermal adsorption experiments on Cs(I), the maximum adsorption quantity of chitin and CuHCF were 2.72 mg/g and 18.5 mg/g and CuHCF was about 6 times higher than chitin. Chtin and CuHCF were found to be specific adsorbents which were not influenced by ionic strength. As a result, CuHCF modified with chitin and Cu and HCF could be used as an adsorbent for the efficient treatment of wastewater contaminated with Cs(I). |
