Abstract

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 50 mg/L 2,4,6-tri-nitrophenol under the conditions of 2 cm distance between the electrodes, pH=7~8 and 25 ℃.

Key words: electrochemical degradation, Polymerization, tre-nitrophenol, Ti/nanoTiO2-Pan
