摘要
过硫酸盐溶于水会生成过硫酸根离子(S_2O_8^(2-)),活化后会生成强氧化性的硫酸根自由基(SO_4^-·),在处理有机废水时可有效降解有机污染物,发展前景良好。本文介绍了热活化、光活化、过渡金属离子活化、零价铁活化、电化学还原、微电解活化等不同活化技术的国内外研究进展,主要涉及活化过硫酸盐的技术的反应机理和应用效果,并对新型过硫酸盐活化技术的发展进行了展望。
Dissolving persulfate in water can produce persulfate ion(S2O8^2-), which will generate strong oxidizing sulfate radical(SO4^-·) after activation. It can effectively degrade organic pollutants in the treatment of organic wastewater, and has good development prospects. In this paper, the research progress of different activation technologies was introduced, such as thermal activation, photoactivation, transition metal ion activation, zero-valent iron activation, electrochemical reduction, microelectrolysis activation, and so on. The reaction mechanism and application effect of activated persulfate technology were discussed. And the development trend of persulfate activation technology was forecasted.
