Formation of Undesired Oxidation Byproducts in Advanced Oxidation Processes (AOPs)

Dear Colleagues,

Advanced oxidation processes (AOPs) are viable approaches to degrade or detoxify contaminants resistant to conventional water treatment processes. They can be used alone or in combination with other treatment processes to address a wide spectrum of organic contaminants. The distinct feature of AOPs is the generation and participation of highly reactive oxidation species such as hydroxyl radicals and sulfate radicals. Generally, organic contaminants are mineralized to CO₂ and H₂O ultimately in AOPs. However, more and more studies have demonstrated that some undesired oxidation byproducts, either organic or inorganic, can be formed in AOPs. The formation of hazardous byproducts may depend on specific water matrices or oxidants applied. This Special Issue of Water is dedicated to sharing recent findings on the formation and control of undesired oxidation byproducts in AOPs.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
