在此研究當中，我們利用電化學氧化法礦化10 mM 草酸，當利用氯離子處理草酸時，可以在電場中產生次氯酸，並對草酸有效礦化。如果處理對象為2mM草酸，可以將礦化率提高至95%以上，並且符合4 mg/L 的飲用水TOC 標準。在實驗中我們也發現，利用電化學氧化法所處理掉的草酸，會直接礦化成為二氧化碳及水，而不會有其他之中間產物。同時也比較了市售之漂白水，還有電化學氧化在陽極產生之次氯酸，發現以本實驗中所產生之次氯酸效果為佳。
而當利用電解芬頓法處理草酸時，發現除了在陽極會有次氯酸生成，溶液中之二價鐵也會在陽極被氧化成三價鐵，導致草酸礦化率下降。而pH 值在本實驗中也扮演了重要之角色，如果可以在低pH 值中操作，礦化率也會相對提升。
另外，在不同之操作條件下，我們也計算出了kobs 值。而利用電解芬頓系統處理實廠廢水時，我們發現因為次氯酸之存在，可將芬頓法處理所產生之中間產物，進一步氧化，並將廢水之COD 值去除約99%。

In this study, we utilize electrochemical oxidation process to mineralize 10 mM oxalic acid. It shows great TOC removal efficiency when using Cl- as solution anion,
due to the formation of hypochlorite on the anode. Over 95% of TOC is removed to meet 4 mg/L of the standard of drinking water when 2 mM of oxalic acid is treated.
In the electrogenerated hypochlorite system, oxalic acid is mineralized into CO2 and H2O without formation of any other intermediates. We also find that the degradation of oxalic acid by electrogenerated hypochlorite is better than the chemical dosage of commercial hypochlorite solution.
We also utilize electro-Fenton system to treat oxalic acid. It is found that except for the Cl- oxidized on the anode, the existence of Fe2+ may also be oxidized
on the anode. Therefore, the mineralization efficiency of oxalic acid decreases. pH value is a major factor that affect the mineralization efficiency. If the solution pH
could be kept at low value, better TOC removal could be reached.
In addition, we also calculate the observed reaction constant kobs with different condition of operation.
When industrial wastewater is treated, almost 99% of COD could be removed when electro-Fenton process is utilized due to the large amount of Cl- contained in the solution that can oxidize the intermediate.
