摘要
采用阴极电沉积方法在多排石墨芯(MRGC)基体上制备NiHCF薄膜,考察二电极体系下膜电极对溶液中Cs离子的置入和释放行为及其影响因素,并通过循环伏安法考察膜的再生性能。结果表明,当初始浓度为20mg·L-1时施加7V电压还原30min,Cs+去除率达84%;Cs/Na混合溶液中的分离系数可达40;氧化再生释放率达到61%。MRGC基体NiHCF膜电极在二电极体系下能有效分离模拟液中的Cs离子,且具有良好的再生能力。
The electroactive NiHCF thin films for electrochemically controlled ion separation （ECIS） were deposited cathodically on the multi-row graphite core （MRGC） substrates. A two-electrode system was used to investigate the separation behavior of Cs^＋ with the MRGC film electrodes, and the regeneration capability of NiHCF thin film was also studied by cyclic voltammetry （CV）. The results show that the removal ratio of Cs^＋ researches 84% after 30 min reduction, when the potential is 7 V and initial cesium concentration is 20 mg·L^-1; and the deintercalate ratio of the oxidization is 61%. The MRGC NiHCF film electrodes can be used to separate Cs ion effectively in the two electrodes system and have good regenerability.
