제목 Electrochemical separation of Cs using a nickel hexacyanoferrate/graphene oxide composite film
초록 We investigated the electrochemical behavior of a nickel hexacyanoferrate/graphene oxide (NiPB/GO) composite coated on electrode. NiPB/GO composite showed electrochemically switched ion exchange capability, and selectivity for Cs over other alkali cations. In experiments to evaluate the stability of NiPB/GO composites, we found that the repeated potential cycling rather improved its cation uptake capacity. In particular, this electrochemical treatment such as potential cycling as well as constant potential method, significantly enhanced Cs uptake compared to that of NiPB/GO and still retained the ion selectivity of NiPB. The electrochemically treated NiPB/GO composite can be applied to the electrochemical separation of radioactive Cs for nuclear wastewater treatment.
