Dear Colleagues,

The development of civilization has brought about an increasing demand for consumer goods, and changes in people's living standards and production lifestyles have been accompanied by an increasing burden on the environment. Water pollution has always been an important environmental issue of concern to countries around the world. Compared with the past, more and more hard-to-degrade persistent organic compounds are entering the environment in the form of domestic sewage and industrial wastewater discharge, which seriously pollute the water environment. At the same time, the presence of emerging organic pollutants poses new challenges to water safety. The development of an efficient organic wastewater treatment technology that is recyclable, environmentally friendly, and non-polluting with low cost is of great significance for society to achieve sustainable development.

Existing articles show that advanced oxidation technology has been applied in water treatment, and the overall treatment effect is good. Advanced oxidation technology has significant advantages in water treatment, but it requires some specific conditions to perform well. Currently, there are still some knowledge gaps in the literature. For example, different types of wastewater quality and treatment conditions often affect the production of reactive radicals and reduce the oxidation efficiency of the treatment process. Advanced oxidation technology also has the problem of higher costs. The current aim is to improve the application conditions of advanced oxidation technology to make it more efficient and stable in water treatment, while at a cheaper cost.

This Special Issue invites original and high-quality research papers and review papers on "Advanced Oxidation Technology for Water Treatment". The collection of relevant papers in this scope helps to improve the effectiveness of advanced oxidation technology in water treatment, to investigate its degradation mechanism and to reduce the cost in the actual treatment process.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Recent research progress of advanced oxidation technology;
• Development and application of new photocatalytic materials;
• Degradation kinetics of pollutants;
• Qualitative and quantitative studies of reactive free radicals;
• Identification of degradation by-products;
• Ecotoxicological assessment and toxicity calculations;
• Reduce the application cost of advanced oxidation technology;
• Application of Density Functional Theory calculations in advanced oxidation research.

We look forward to receiving your contributions.
