Ultrasonic-assisted ozone degradation of organic pollutants in industrial sulfuric acid

“…In metal smelting processes, organic pollutants introduced by metal minerals, fuels or flotation agents, which are not completely removed in the purification system, enter sulfuric acid products. For industrial sulfuric acid with high organic content, although the high-temperature pyrolysis method can effectively remove organic pollutants and produce high-quality fresh sulfuric acid, its application is limited due to huge equipment and operating costs [11] . At the same time, the extraction and adsorption methods [12] , [13] have several shortcomings, such as poor removal effect, large amount of adsorbent and low reuse efficiency.…”
