Contaminants of Emerging Concern Removal by High-Energy Oxidation-Reduction Processes: State of the Art

摘要: The presence of ‘emerging contaminants’, i.e., chemicals yet without a regulatory status and poorly understood impact on human health environment, in wastewater aquatic environments is widely reported. No established technology, to date, can simultaneously completely remove all these contaminants, even though some Advanced Oxidation Processes (AOPs,) have demonstrated capacity for degradation compounds. High-energy, radiolytic processing water matrices using various sources: electron beam (EB), ɣ-rays or non-thermal plasma (NTP) has shown excellent results many applications, although remain at the moment isolated examples scarcely known. High-energy irradiation constitutes an additive-free process that uses short-lived, highly reactive radicals (both oxidating reducing) generated by radiolysis, which instantaneously decompose organic pollutants. Several studies its effectiveness, as stand-alone combined with others, rapid decomposition (up complete mineralization) compounds pure complex solutions, removal inactivation microorganisms parasites, production leftover residual solution. oxidation processes (a.k.a. & Reduction Processes—AORPs) could primary role future strategies addressing emerging contaminants.
