In this study, initialy the effect of time on the removal of strontium from aqueous solutions by continuous electrodeionization (CEDI) with H+ form resin was investigated. Then, by using an orthogonal L9 array in the Taguchi method, the effect of voltage, flow rate and feed concentration on the removal of Sr and Cs from aqueous solutions by the CEDI with the saturated resin was applied. The analysis of variance (ANOVA) method was used to evaluate the relative effect corresponding to each factor. The results showed that by increasing the applied voltage and decreasing the flow rate improve the performance. The effect of input voltage was more significant and the feed concentration did not have any perceptible effect on the Sr and Cs removal efficiency. The removal of both elements from binary solutions were also investigated. In this experiment, the removal efficiency of Sr was also found to be higher than those of Cs. Based on the results, electrodeionization was considered to be effective for Sr and Cs removal from aqueous solutions.
