The radiation by non-thermal plasma can accelerate formaldehyde thansform and make an increase of 29.61% in depurated efficiency. The surface modification makes no obvious difference in depurated efficiency. The chemical modification avails formaldehyde reduction and ACF coated with nano- TiO2 is the best of all that can enhand the depurated efficiency to 94%. The great influence of parameters on depurated efficiency , such as applied voltage and reaction time , shows that an increase in either applied voltage or reaction time enhance formaldehyde conversion.
