• 中文摘要： 利用在連續攪拌電解槽中，電解還原水溶液中之溶氧與氧化氯離子生成之過氧化氫與次氯酸降解甲醛。在溶液不含甲醛之條件下，當氣體的流率從100加至 300ml min/sup -1/時電解生成過氧化氫與次氯酸之電流效率分別由77.5與 55.8%增加至91.9與73.7%。當氣體流率從100增加至300ml min/sup -1/時，甲醛之總降率從9.09增加至10.98%，而組對降解甲醛之電流效率則從123.5增加至 151.9%。當氣體流率小於250ml min/sup -1/時，在陽極與陰極室中所進行之甲醛降反應均處於質傳控制區。
• 英文摘要： Hydrogen peroxide and hypochlorite electrogenerated by the cathodic reduction of dissolved oxygen and the anodic oxidation of chloride ion were employed to degrade formaldehyde in a continuous-flow stirred-tank electrochemical reactor (CSTER). The current efficiency for producing hydrogen peroxide and hypochlorite in the absence of formaldehyde increased from 77.5 and 55.8% to 91.9 and 73.7%, respectively, when the gas flow rate increased from 100 to 300ml min/sup -1/. For the gas flow rate ranging from 100 to 300ml min/sup-1/, the total degradation fraction of formaldehyde increased from 9.09 to 10.98% and the total current efficiencies of the paired oxidative degradation of formaldehyde increased from 123.5 to 151.9%. The degradation of formaldehyde in both of the anodic and cathodic chambers was controlled by the mass transfer rate when the gas flow rate was less than 250ml min/sup -1/.
