微型電解裝置之設計研究
Studies on the Designs of the Microscale Laboratory for Electrolysis of Water
摘要
本文僅利用塑膠滴管、塑膠量筒、塑膠注射筒、注射針、三通塑膠活栓及塑膠小試管等分別組合成四套「微型電解裝置」，一為「吸取式微型電解裝置」；二為「注入式微型電解裝置」，三為「抽取式微型電解裝置」以及四為「何夫曼(Hofmann)微型電解裝置」。本文因器材簡單、製作容易，每位學生皆可自製，各擁有一套，增加自己動手做實驗的機會，為一兼具有教學、實用、趣味性以及兼具有『可回收、低污染、省資源』環保理念之「微型化學實驗裝置」，採用微型化學實驗儀器，可以節約試劑和時間，並得以訓練學生細心操作的實驗技巧與能力，使教師得以在有限的時間與經費之下，來完成實驗教學的要求，可增進化學實驗之教學成效，頗值得在國中理化實驗及高中、高職或大學化學實驗中加以推廣使用。

The advantages of microscale laboratory (M.L.) are well known , especially in chemical education. There are three purposes of microscale laboratory for electrolysis of water, including (1) improving the manipulation skills of the students, (2) developing the students with innovated thinking, and (3) consolidating the environmental awareness of the students. Four new designs of microscale experimental apparatus for electrolysis of water are described. Plastic syringes, plastic graduated cylinder, two-way plastic stopcocks, three-way plastic stopcocks, plastic boxes, plastic tubes and some small materials are used in the new experiments described. The new design allows the electrolysis of water to be carried out and tested easily, and accurately. With new simple apparatus, the amount of chemicals consumed and a waste produced in these experiments is greatly reduced compared to those traditionally.
