NanoTiO2-聚苯胺复合膜电极电化学降解2,4,6-三硝基苯酚
Electrochemical Degradation of 2,4,6-Tri-nitrophenol Using Electrodes of Ti/nanoTiO2 -PAn
摘要
Abstract
Polymerization of aniline on nanoTiO2 complex film electrode was achieved by sol-gel method and electrochemical polymerization technique. XRD, SEM and CV were used to characterize the structure and image of the nanoTiO2-PAn complex film. Loose short fiber and porous structure could be observed by SEM. The average particle size of crystal grains was 150 nm. The COD removal efficiency reached 41. 2% for an artificial wastewater containing SO mg/L 2,4,6-tri-nitrophenol under the conditions of 2 cm distance between the electrodes, pH =7 ~8 and 25 ℃.关键词
