UV/ H۲O۲ Advanced Oxidation Process for Simultaneous Removal of NO and SO۲: A Review

This study presents a review on advanced oxidation processes (AOP) for simultaneous removal of NO and SO۲. AOP is based on using a strong oxidant such as ozone and H۲O۲ which is able to generate highly reactive intermediates. The pollutant will be oxidized and removed by these intermediates. In recent years, AOP has been considered as an effective and attractive technology in the field of flue gas purification. In this paper, first, a brief overview on conventional methods for NOx removal is presented. Then the concepts of AOP are explained and the different AOPs are introduced. Since, H۲O۲ is widely used as   a chemical oxidant in advanced oxidation processes, the most attention in this article is paid to the advanced oxidation with H۲O۲. On the other hand, the photochemical method (applying UV light) for producing active radicals in advanced oxidation process has become an attractive issue in recent years. Thus, the main focus of this study is  on UV/H۲O۲  advanced oxidation process. The concepts, status of progress and attractive issues for future researches are discussed. .
