添加剂对等离子体降解亚甲基蓝的影响
The effects of additives on the degradation of methylene blue using plasma
摘要
Abstract
With the development of industry,water pollution as one of the environmental issues has been paid more and more attention around the world. Organic wastewater,which is highly toxicity and difficult to degrade,has become a serious problem in recent years. Dielectric barrier discharge(DBD) plasma can cause a variety of physical and chemical effects,which combines ozonation,ultraviolet degradation, pyrolysis,free radical oxidation in one technology,providing a new method for aqueous organics control. In the present work,the effects of additives on the degradation of methylene blue(MB) using self-design double-chamber DBD reactor was studied. Under the same experimental conditions,adding NaCl,Na2SO4 or NaNO3 had little effect on MB degradation,adding NaHCO3 or Na2CO3 weakened MB decomposition process using plasma,while adding Na3PO4 or NaNO2 has serious inhibited MB degradation. After adding Na3PO4 or NaNO2,the degradation efficiency of MB was 1/3 of that with no additives under the same experimental conditions. Scavenger of ·OH(t-butanol)would inhibit the degradation of MB,while scavenger of ·H(CCl4) has little promotion effects on MB degradation. In addition,the addition of Fe2+ has limited role in promoting the decomposition of MB.关键词
