摘要

湿度对挥发性有机化合物(VOCs)非热等离子体处理过程中表面放电的影响进行了广泛的研究，因为假设等离子体中产生的活性OH自由基会分解空气中污染的稀释voc。对1000ppm CFC-113污染的样品空气湿度采用鼓泡法控制，水温分别为7、17、45、70。在干燥空气条件下，CFC-113的分解效率稍好。三氯乙烯的分解效率不受湿度的影响。

Humidify effect on non-thermal plasma processing for VOCs decomposition

Humidity effects on surface discharges induced in nonthermal plasma processing for volatile organic compounds (VOCs) decomposition was studied extensively, because reactive OH radicals generated in the plasma are assumed to decompose dilute VOCs contaminated in air. The humidity of sample air contaminated with 1000 ppm CFC-113 was controlled with water bubbling where the water temperatures were 7/spl deg/C, 17/spl deg/C, 45/spl deg/C and 70/spl deg/C. The decomposition efficiency of CFC-113 was a little better in the dry air case. The decomposition efficiency of trichloroethylene was not affected by humidity.
