摘要

研究主要是利用電化學氧化方式去再生離子對，之後將再生之離子對去對硫化氫氣體進行吸收處理，並比較再生之離子對吸收硫化氫氣體的效果。在本研究中，將以電化學方法對二價鐵離子和三價鐵離子之離子對與氯離子和次氯酸根離子之離子對進行氧化再生。實驗方法是將離子對進行直接電化學法來再生，並找出再生離子對的最佳操作參數條件。
本研究判斷電化學氧化程序再生離子對的過程中，電解質氯化鈉的影響會比通電電流所帶來的影響大得多。當比較不同電解質氯化鈉濃度對離子對的再生率影響時含有高電解質濃度的實驗參數組，其離子對的再生率會比低電解質濃度的實驗參數組還要高，且高電解質濃度的實驗參數組再生出之離子對，去對硫化氫氣體進行吸收處理的效果，比低電解質濃度的實驗參數組再生出之離子對的效果還要好，因此為了分辨出是再生出之離子對還是電解質氯化鈉所產生之氧化劑(次氯酸根離子)對硫化氫氣體的吸收效果較好而做比較。

The objective of this study is using the electrochemical oxidation method to regenerate the ion pair, then use the regeneration of the ion pair to the treatment of the hydrogen sulfide gas absorption, and compare the regeneration of the ion pair on the effect of hydrogen sulfide gas absorption. The experimental method is directly regenerate the ion pair by electrochemical, and to find the optimal operating parameters for the ion pair of regeneration.In this study, the effect of electrolyte sodium chloride on the electrochemical oxidation process is much greater than the current of operation. When comparing the concentration of sodium chloride with different electrolyte concentration on the regeneration rate of the ion pair, the regeneration rate of the ion pair with the experimental parameter of high electrolyte concentration is higher than the experimental parameter of low electrolyte concentration, and the treatment effect of hydrogen sulfide gas absorption is the regenerated ion pair with the experimental parameter of high electrolyte concentration better than the regenerated ion pair with the experimental parameter of low electrolyte concentration. Therefore, do this comparison is in order to distinguish whether the regenerated ion pair or the oxidant (hypochlorite ion) produced by the oxidation of electrolyte sodium chlorine on the effect of hydrogen sulfide gas absorption is much better .
