中文摘要 | 本文是利用發射攝譜儀來檢驗天然水及處理水中之銀元素的含量。基於自來水中所含有之元素對於銀元素均無干擾作用,因此這種方法是較優的銀檢驗法。雖然此方法需相當的特殊訓練及經驗,但是它可以彌補若干其他方法 (例如二硫仲比色法) 不容易檢驗或準確度差的缺點。至於分析的方法是,選擇適當的分析線偶,以內標準法來分析自來水中之銀元素的濃度。在分析過程中,將水樣予以低溫真空濃縮,可檢測較低濃度的水樣,本文中並附有分析過程中之樣品的光譜圖以及分析結果。 |
英文摘要 | The subject of this paper is on how to apply the emission spectrocopy to exarnine the quantity of the silver element in drinking water. This method is superior to the dithizone method, which cannot examine the quantity of silver accurately, due to the fact that dithizone can be easily ionized by strong light. Instead of the widely used method, the researcher suggest using the emission spectroscopy to analyze the silver element in tap water. It is because almost no spectroscopic line of the other elements in the liquid can interfere with that of the silver element; the result, thus, is more likely to be accurate. As for the analysis, the internal standard method is adopted; the analysis pair guides to get the condensity of the silver element in tap water. In the analytical process, the sample water is to be vaporized; (to condense the water to 10 mL per liter); the higher condensity of the sample grants better results. At the end of the paper, the spectroscopic lines are enclosed to indicate the position of the analysis pair. |
