Desalination of saline water was carried out by capacitive deionization (capDI) method. Pseudocapacitive materials (CoFe₂O₄/Fe₂O₃) were coated on the carbon cloth as capDI electrode for three different reaction time (6, 9 and 12 h). Synthesized capDI electrodes were characterized using SEM, XRD, Raman and XPS. The desalination was tested by batch method to study the desalination performance of the synthesized electrode. The results showed that 89% and 30 % of desalination efficiency at 200 and 500 mg/L (1500 μS/cm initial conductivity), respectively for 6 h reaction time sample. The adsorption of inorganic ions from the saline water on 6 h sample was found to be about 30 mg/g at an initial concentration of 500 mg/L. The kinetic analysis indicated that the electrosorption of NaCl on capDI electrodes followed pseudo‐first order kinetics model. Overall, the developed pseudocapacitive capDI electrode was able to desalinate NaCl by capacitive deionization method under experimental condition.

碳布上的CoFe2O4 / Fe2O3作为无粘合剂电极用于电容去离子方法进行脱盐

盐水的脱盐是通过电容去离子（capDI）方法进行的。伪电容材料（CoFe ₂ O ₄ / Fe ₂ O ₃）涂在作为capDI电极的碳布上三个不同的反应时间（6、9和12 h）。合成的capDI电极使用SEM，XRD，拉曼和XPS进行表征。采用间歇法对脱盐性能进行了测试，以研究合成电极的脱盐性能。结果表明，在6 h反应时间的样品中，分别在200和500 mg / L（1500μS/ cm的初始电导率）下的脱盐效率分别为89％和30％。发现初始浓度为500 mg / L时，盐水在6 h样品上的无机离子吸附量约为30 mg / g。动力学分析表明，NaCl在capDI电极上的电吸附遵循伪一级动力学模型。全面的，
