AOPs have a wide range of applications in water treatment, air purification, and soil remediation. In water treatment, AOPs are used to degrade micro-pollutants, disinfect pathogens, and remove color and odor. For air purification, these processes help in breaking down volatile organic compounds (VOCs) and other airborne contaminants. In soil remediation, AOPs can detoxify contaminated soil by degrading organic pollutants.
