Review of recent developments in electrochemical advanced oxidation processes: application to remove dyes, pharmaceuticals, and pesticides

Accelerated Photolysis of H2O2 at the Air–Water Interface of a Microdroplet

“…8,9 •OH is also involved in the transformation of pollutants, such as pesticides, pharmaceuticals, and other organic contaminants. 10,11 Understanding the role of •OH in these processes is vital for predicting and mitigating the impacts of environmental pollution on human and ecosystem health.…”

“…Hydroxyl radicals (·OH) are highly reactive species that are found throughout nature and are involved in a wide range of important chemical reactions. , In the atmosphere, ·OH is responsible for driving the rapid conversion of gaseous pollutants, such as volatile organic compounds (VOCs) and nitrogen oxides (NO x ), into secondary organic aerosols (SOAs) and nitrate. These chemical reactions are crucial in the formation and growth of fine particles during haze events, which can have severe environmental and health impacts. − Additionally, ·OH plays an essential role in the oxidation of sulfur dioxide (SO 2 ) into sulfate and the deposition of acid rain, which can harm aquatic and terrestrial ecosystems. , In aquatic systems, ·OH is a crucial player in accelerating the cyclings of elements, such as the oxidation and mineralization of organic carbon. , ·OH is also involved in the transformation of pollutants, such as pesticides, pharmaceuticals, and other organic contaminants. , Understanding the role of ·OH in these processes is vital for predicting and mitigating the impacts of environmental pollution on human and ecosystem health.…”

Current Mechanism of Peroxymonosulfate Activation by Cobalt-Based Heterogeneous Catalysts in Degrading Organic Compounds

“…Water pollution remains a persistent and complex issue in global environmental protection, compounded by the escalating concentration of emerging pollutants such as pharmaceuticals, personal care products (PPCPs), and endocrine disrupting chemicals (EDCs). These emerging pollutants are particularly concerning due to their toxicity and resistance to degradation, posing significant threats to both human health and the environment. − Conventional sewage treatment methods have proven inadequate, and environmental policies are driving the need for technological upgrades. , Advanced oxidation processes (AOPs) are highly anticipated as a potential solution, due to their ability to mineralize organic compounds (OCs) into harmless byproducts via the production of reactive oxygen species (ROS) with high oxidation potential. , AOP can treat wastewater from multiple sources and is capable of transforming waste into catalysts necessary for this progress, making it an ideal candidate for sustainable green development. − …”

Photo‐Alternating Current‐Electro‐Fenton Process for Pollutant Removal and Energy Usage from Industrial Wastewater: Response Surface Approach Optimization of Operational Parameters

“…EAOPs are used extensively for the removal of a wide variety of organic/inorganic pollutants, including pharmaceutical, [26,27] dyes, and pesticides, [27] chloride wastewater, [28] textile industry, [29] cosmetics waste, [30] landfill leachate, [31] refractory oil wastewater, [32] micro-pollutants, [33] persistent organic pollutants, [34] and etc. The increase in the quantity of * OH, found in the electrolytic cell may be attributed to the combination of light irradiation and EAOPs.…”
