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.

研究结果表明：低温等离子体辐射能促进甲醛净化，可使其净化效率提高29.61%；表面改性对净化效率没有明显影响；化学改性有利于甲醛净化，其中负载纳米TiO2改性方案最佳，其净化效率高达94%；电源电压和反应时间等参数对净化效率也有较大影响，电压越大，时间越长就越有利于甲醛的去除。
