A CNT-based electrode was prepared using dispersed multi-walled CNTs and anionic polyurethane binder as the dyestuff for coating CNTs on polyester yarns, followed by washing with ethanol to remove the binder. The resulting CNT-based electrode with a CNT network on surface, has a high special surface area and a high electrochemical activity, making it useful for the removal of phenolic compounds from the contaminated water. Through electrochemical polymerization and degradation on this electrode, high removal efficiency of bisphenol A was obtained, at levels as high as 8.1 x 10(-5) mol/g with 0.75 V applied potential.
