本研究利用富有纖維結構之絲瓜絨作為生物質原料、氯化鋅作為活化劑進行化學活化法製備具高比表面積、多孔材質活性碳，並探討活化溫度對活性碳基本特性之影響。後續以過錳酸鉀還原法製備活性碳負載二氧化錳於活性碳上作為電極使用，透過電化學氧化方式氧化在高級氧化技術(AOPs)中主要中間產物草酸和常見之無機酸。在反應動力上，提出動力模型，並根據實驗所得之草酸濃度與錳濃度，推算出反應速率常數及闡述其在反應中代表之意義。研究結果發現二氧化錳可氧化草酸使溶液的總有機碳(TOC)濃度下降，但是碳電極本身的氧化造成反應後期TOC濃度上升，TOC去除率有回升現象。溶液中錳回收方面則是與反應pH值息息相關，然而，透過熱處理後二氧化錳有晶型轉換現象發生，對於改善錳回收有正面之影響。二氧化錳對於氧化無機酸的能力上亦有差異，其中對於亞硝酸氧化能力最好，可於120分鐘內將亞硝酸完全氧化為硝酸。

Due to the scarcity of available water resources, many researches are devoted to water desalination and recycling. Capacitive deionization (CDI) is one of the main technologies for treating seawater desalination. This study aims at developing electro-adsorption and oxidation process to treat the common organic/inorganic acids in water based on the mechanism of capacitive desalination. Loofah sponge is utilized as precursor to fabricate activated carbon (AC) by chemical activation. The influence of pyrolysis temperature on the characteristics of activated carbon was investigated. The activated carbon-supported manganese dioxide (MnO2) was prepared by reducing potassium permanganate and characterized by X-ray diffraction (XRD). The results of electrochemical experiments showed that manganese dioxide oxidized oxalic acid and reduced the total organic carbon (TOC) concentration of the solution, but the oxidation of the carbon electrode caused to an increase of TOC in the later stage of the reaction. Inorganic acids also were oxidized, however, the low adsorption capacity of the electrode was incapable of removing oxyanions.
