基于过硫酸盐的高级氧化技术英语
Advanced oxidation technologies based on persulfate have been widely studied and applied for the treatment of various environmental pollutants. Persulfate, also known as peroxodisulfate, is a powerful oxidizing agent that can generate sulfate radicals (SO4•−) under certain conditions. These sulfate radicals are highly reactive and can effectively degrade organic compounds through a series of oxidation reactions.
One of the key advantages of persulfate-based advanced oxidation technologies is their ability to degrade a wide range of organic pollutants, including persistent and refractory compounds. This makes them suitable for applications in the treatment of contaminated groundwater, industrial wastewater, and soil remediation. Persulfate can be activated by various methods, such as heat, UV light, transition metal ions, and other chemical additives, to enhance its reactivity and efficiency in pollutant degradation.
The mechanism of persulfate activation involves the generation of sulfate radicals through the decomposition of persulfate molecules. These sulfate radicals can then react with organic
pollutants to form intermediate products, which eventually degrade into harmless byproducts such as carbon dioxide, water, and inorganic ions. The degradation efficiency of persulfate-based advanced oxidation technologies is influenced by various factors, including pH, temperature, persulfate concentration, type of pollutants, and presence of catalysts or co-oxidants.
In recent years, persulfate-based advanced oxidation technologies have been successfully applied in the treatment of emerging contaminants, such as pharmaceuticals, personal care products, and pesticides. These contaminants are often present in trace amounts in water bodies and can pose risks to human health and the environment. Persulfate-based advanced oxidation technologies offer a cost-effective and sustainable solution for the removal of these emerging contaminants from water sources.
Overall, persulfate-based advanced oxidation technologies have shown great potential in the treatment of environmental pollutants due to their high reactivity, versatility, and effectiveness in degrading a wide range of organic compounds. Continued research and de
velopment in this field are needed to optimize the performance of persulfate-based advanced oxidation technologies and further expand their applications in environmental remediation.
基于过硫酸盐的高级氧化技术已被广泛研究和应用于各种环境污染物的处理。过硫酸盐，也称为过氧化二硫酸，是一种强氧化剂，在一定条件下可以产生硫酸根自由基（SO4•−）。这些硫酸根自由基具有很高的反应性，可以通过一系列氧化反应有效降解有机化合物。
基于过硫酸盐的高级氧化技术的一个关键优势是其能够降解各种有机污染物，包括顽固和难降解的化合物。这使得它们适用于受污染的地下水、工业废水和土壤修复等领域的应用。过硫酸盐可以通过加热、紫外光、过渡金属离子和其他化学添加剂等方法激活，以增强其在污染物降解中的反应性和效率。
过硫酸盐激活的机制涉及通过过硫酸盐分解生成硫酸根自由基。这些硫酸根自由基然后可以与有机污染物反应，形成中间产物，最终降解为无害的副产物，如二氧化碳、水和无机离子。基于过硫酸盐的高级氧化技术的降解效率受多种因素影响，包括pH值、温度、过硫酸盐浓度、污染物类型以及催化剂或共氧化剂的存在。
