Special Issue Information

Dear Colleagues,

The overuse of Pharmaceutical and Personal Care Product (PPCP) worldwide in the last decade has posed serious adverse effects on the aquatic environment and human health. Thus the PPCP removal has arouse global concerns and tremendous research interests among the environmental scientists and engineers. The conventional wastewater treatment approaches such as activated sludge process cannot effectively remove the aqueous PPCP which exhibit non- or poor biodegradability to the microorganisms. In comparison, the advanced oxidation processes (AOP) has demonstrated high capability for decomposing the recalcitrant organic pollutants with the strong oxidative species generated during the processes. In addition, the water scarcity and energy crisis have been regarded as the two of the most serious environmental issues in both developed and developing areas. And the water reclamation and energy recovery such as hydrogen evolution during the catalysis-based wastewater treatment processes have received broad attentions. This special issue aims to cover the recent progresses and advances in designing and characterization of novel catalyst, novel AOP for high-rate decomposition of PPCP, AOP for wastewater treatment and reuse and catalytic processes for simultaneous wastewater purification with hydrogen evolution.

The scope of interests

1) Novel advanced oxidation processes for enhancing emerging pollutants degradation

2) Advanced oxidation processes for wastewater treatment and reclamation

3) Synthesis of novel catalysts for remediation of environmental pollution

4) Simultaneous catalytic degradation of emerging micropollutant and hydrogen evolution from wastewater

5) Integrated AOP with biological technologies for advanced wastewater treatment and reuse

Oxidative stress induced by fine particulate matter 2.5 (PM2.5) is a potential cause of adverse health effects owing to the production of reactive oxygen species (ROS). Air filtration is a key technology for preventing exposure to particulate contaminations; however, particulate matter trapped by filters has the potential risk of human contact with condensed PM2.5. Thus, this study aims to reduce the hydroxyl radical (·OH) production potential of PM2.5 collected on such TiO2-supporting quartz filters. The ·OH production potential was evaluated for PM2.5, which was collected in Kanagawa, Japan, using a terephthalate assay coupled with flow injection analysis. Although the PM2.5 levels at the sampling site were not severe, the PM2.5 samples exhibited ·OH production potential, which was mostly attributed to organic aerosols. The effect was verified using a TiO2-supporting quartz filter for the collection and subsequent degradation of PM2.5. The ·OH production potential was significantly reduced from 0.58 ± 0.40 pmol/(min m3) to 0.22 ± 0.13 pmol/(min m3) through ultraviolet irradiation for 24 h. This suggests that the photocatalytic reaction of the TiO2 filter is effective in reducing the ·OH production potential of PM2.5. Full article
