Publikováno v: Journal of Water and Health. 17:254-265

In this study, the kinetics of photocatalytic removal of imidacloprid, a systemic chloronicotinoid insecticide, from water using two advanced oxidation systems (ZnO(normal)/H2O2/artificial sunlight and ZnO(nano)/H2O2/artificial sunlight) were investi

Singlet Oxygen Photogeneration in Coastal Seawater: Prospect of Large-Scale Modeling in Seawater Surface and Its Environmental Significance

Autor: Michael Oluwatoyin Sunday, Kazuhiko Takeda, Hiroshi Sakugawa

Publikováno v: Environmental sciencetechnology. 54(10)

Chromophoric-dissolved organic matter (CDOM) acts as the precursor to singlet oxygen (1O2) in natural waters, while water acts as the main scavenger. In this study, we showed that 1O2 in coastal seawater can be successfully predicted from CDOM parame

Publikováno v: The Science of the total environment. 733

Hydrogen peroxide (H2O2) is a reactive oxygen species formed in natural water. It is reportedly toxic to aquatic organisms with a predicted no-effect concentration (PNEC) of about 380 nM. In this study, a countrywide investigation of H2O2 concentrati

Photoformation of reactive oxygen species and their potential to degrade highly toxic carbaryl and methomyl in river water

Autor: Kazuhiko Takeda, Hiroshi Sakugawa, Michael Oluwatoyin Sunday, Aly Derbalah, Ryota Kato

Publikováno v: Chemosphere. 244

Reactive oxygen species (ROS) including singlet oxygen (1O2) and hydroxylradicals (radical dotOH) photogenerated in natural waters play important roles in indirect photolysis of man-made pollutants. This study was conducted to investigate how the gen
