Abstract:

Based on the advantages of available micro plasma technology, our modified microwave plasma reactor was used for the degradation of two principle air pollutants, formaldehyde (HCHO), sulfur dioxide (SO₂). The experimental results show that HCHO as well as SO₂ were degraded significantly. The effects of the discharge current, carrier gas flowrate and types, inlet HCHO and SO₂ concentration and pH were also investigated and their contributions to the degradation were explained.
