    摘要: 由於以往在工常上及農業上大量的使用鹵化有機物,而這類汙染物質通常是與土壤及水沈積物結合而存在,加上在土壤及水沈積物中其自然分解速率緩慢而纍積於其中,使得鹵化有機汙染物普遍存在目前的環境中。本研究利用自製的鉛電極以及含催化性金屬錯合物的厭水性鉛複合電極,分別探討二溴聯苯、二氯聯苯及五氯氛的CV電化學性質。其次,利用添加方式探討超音波振盪萃取土壤中二溴聯苯、二氯聯苯及五氯氛的萃取效率。此外,利用流動電解槽結合超音波振盪萃取設計完成一流動電解系統。最後,利用ADDA及I/O介面卡及PC完成電解流程自動化的設計。
    Organohalides pollutants are ubiquitous in our environment from past industrial and agricultural usage. Organohalides in the environment are often associated with soils and aquatic sediments. The quantity of organohalides in the environment increased with the time due to the quite slow rate of natural dechlorination in soils and sediments. In this studies, a hydrophobic composite electrode with a organometal catalyst was prepared. The electrochemical characteristics of three organohalides were studied by the detection of cyclic voltametry with the cathode of lead electrode and composite electrode. The design of automatic extractive and electrolytic system, and the extractive and electrolytic efficiencies of organohalides in soil were described.
