摘要
过硫酸盐活化产生的强氧化性硫酸根自由基SO4-.,在环境污染治理领域具有广阔的应用前景。首次详细综述了热、过渡金属离子、紫外光、碱性条件、零价金属Fe0等单一方法,以及双氧化剂、紫外光与过渡金属离子或双氧化剂、超声与热等复合方法活化过硫酸盐的国内外研究进展,并就活化方法与有机物结构及pH之间的关系、SO42-残留等问题进行了阐述。最后,在本课题组研究成果的基础上针对其发展方向进行了展望。
Persulfate oxidation is a recently emerging technology for the pollution control. Produced by activated persulfate, the sulfate free radical SO4^-· ,a powerful oxidant, can degrade most of the organic compounds. This paper, for the first time., provides an up-to-date overview of single activation methods, such as thermal persulfate, photochemical persulfate, persulfate combined with transition metal ions, alkaline persulfate, zero-valent metal Fe^0, and multiplex activation technologies as well including dual oxidant system, and hybrids of single activation method mentioned above. Moreover, the relationship between the activation method and organic structure as well as pH value, and also the residue of SO^2- 4 are discussed. Finally, on the basis of our preliminary, findings, the research trends for promoting its development are prospected.
