© 2018 The Authors. Aluminum electrochemical anodizing dyed products have been widely used in various sectors of industries including cell phone, laptop computers, bikes and aero-space technologies. During the process of aluminum electrochemical anodizing dyeing industry, and waste water which contains dyestuffs tend to be emitted and most of them comes from the color bleeding during the process of sealing; therefore, the topic of how to reduce the color bleeding efficiency during the sealing process and decrease dyed waste water generated becomes a huge environmental issue. In the research, the factors which cause the color bleeding during the sealing process are thoroughly discussed and ratified in a careful manner. Statistical analysis is conducted to analyze how color bleeding is influenced by different dyeing temperatures and various film thickness formed in different time frame of aluminum electrochemical anodizing dyeing. Moreover, aluminum electrochemical anodizing electrode carried out into electrochemical process; the porous oxide film modified electrode is employed to detection of folic acid (FA) in vegetables. The sensor linear range is 0.1 to 897 μM, LOD=54 nM, and sensitivity is 5.18 μA μM -1 cm -2 .
