Advanced Oxidation Technologies in Environmental Wastewater Treatment

Dear Colleagues,

The growing global water crisis underscores the urgent need to implement effective strategies to combat water scarcity. One such approach is wastewater reuse. However, it is necessary to implement treatment technologies that eliminate/reduce the presence of non-biodegradable and/or toxic pollutants as well as inactivate harmful pathogenic microorganisms—particularly those resistant to antibiotics— with the goal of promoting safe reuse, minimizing negative effects in the environment and preserving public health.

Advanced Oxidation Technologies (AOTs) provide a promising and sustainable approach to improve the removal of pollutants and inactivation of pathogenic bacteria and viruses in wastewater, thus enhancing water reuse practices. The highly oxidative radicals generated by AOT(s) are responsible for oxidizing pollutants and promoting cell lysis, thereby improving the quality of treated wastewater. These radicals are formed from various species, including hydrogen peroxide, oxygen, ozone, chlorine and persulfate (among others), particularly through catalysed processes or by direct radiation.

In this Special Issue of Molecules, authors are encouraged to submit original research and review papers focused on the application of homogeneous and/or heterogeneous AOT(s) for wastewater treatment or disinfection.

I look forward to receiving your contributions.

Dr. Carmen S. D. Rodrigues

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 250 words) can be sent to the Editorial Office for assessment.

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. Molecules 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 2700 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.
