摘要

本研究使用熱分解法，藉由銥、鉭兩種不同金屬溶液製備鈦基金屬氧化物電極，使用製備好之電極電催化甲基橙染料廢水。首先，經由不同的實驗控制變因(如金屬溶液配方、金屬溶液塗覆層數及煅燒溫度) 以來探討是否製備出最佳鈦基金屬氧化物電極；製備出最佳電極後再經由不同的實驗控制變因(如電壓、循環水溫、硫酸鈉濃度及染料廢水濃度)探討最佳電催化甲基橙染料廢水參數。
本研究結果顯示，鈦基金屬氧化物電極最佳強化壽命試驗為銥、鉭金屬溶液莫耳比7：3、塗覆層數8層及以450℃煅燒者；最佳電催化染料廢水參數為電壓6 V、循環水溫40℃、電解質硫酸鈉濃度2 g/100ml及甲基橙染料廢水濃度10 mg/L。

Use a thermal decomposition method by this study.By Iridium, Tantalum two different metals for preparation of the Ti-base metal oxide electrodes, and electrocatalytic treatment of dye wastewater. First, due to the different experimental control variables (e.g., metal solution formulation, metal coated layers, and the calcining temperature was up) is prepared by investigating preparation of the Ti-base metal oxide electrodes; Prepared by the best electrode before (such as voltage, temperature cycling, sodium concentration and the concentration of dye wastewater) to explore the best electro-catalytic wastewater methyl orange dye different experimental parameters via the control variable.
The results of this study showed that titanium-based metal oxide electrode life test is best enhanced iridium, tantalum metal solution molar ratio of 7：3, 8-layer coating layers and calcination temperature of 450℃; optimum parameters for the electro-catalytic dye wastewater Voltage 6V, circulating water temperature 40℃, the concentration of the electrolyte sodium 2 g/100ml and wastewater methyl orange dye concentration 10 mg /L .
