| 中文摘要 | 以COD及TOC等綜合指標來表示水中有機物的多寡,為目前常用的方法;在TOC的濕 式氧化法中,氧化劑將有機物氧化成二氧化碳的效率,將影響檢測值的大小,在本實驗中探 討的 Na �� S �� O �唌BH �� O �砟帤f頓試劑等三種氧化劑的反應情形, 發現以 Na �� S �� O �堋�為適用,但因其氧化效率隨有機物的不同而有所不同, 故若能預知待測水樣中之 有機化合物為何物質,而以其為標準品建立檢量線,將可得較準確的檢測結果;COD 實驗的 氧化劑為重鉻酸鉀, 其可能無法有效氧化高濃度的芳香族化合物,而使其 COD 檢測值偏低 。 |
| 英文摘要 | COD and TOC ard usually use for represent the amount of organics in the wastewater. In the wet oxidation, TOC will affect by the level of organic compounds oxidize to CO ��. There ard three oxidizing agents, Na �� S �� O ��, H �� O �� and Fenton's reagent, were investigated in this work and Na �� S �� O �� was found to be an appropriate one for uses. Due to the degree of oxidation depend on the type of organic compounds, analysis will be more accurate if we can know the organic compound in the sample in advance and then the pure compound standard for calibration. Among the COD tests, we found K �� Cr �� O �f is a poor oxidizing agent for aromatic compounds, for example phenol, oxidation. The detected COD will less than actual value if there are aromatic compunds in the sample. |
