Abstract Conventional methods to clean wastewater actually lead incomplete treatments, calling for advanced technologies degrade recalcitrant pollutants. Herein we review solar photo-oxidation the contaminants in industrial wastewater, with focus on photocatalysts, reactor design and photo-Fenton process. We discuss limitations due low visible-light absorption, catalyst collection reusability, ...

• Fe(II) promoted the photo-oxidation of released As(III) in ASS. The mechanism Fe(II)-stimulated was pH-dependent. At pH 3.0, both OH and SO 4 − made a contribution to As oxidation. Reductive sulfur species from ASS played critical role Fe(II)/Fe(III) cycle. Arsenic sulfide sludge (ASS) is typical precipitation product acid smelting wastewater. Previous study reported that when exposed sunligh...

Skin surface lipid (SSL) film is a mixture of sebum and epidermal lipids protecting the skin from effects environment such as solar radiation. SSLs are suitable target scavenger for all reactive oxygen species (ROS) generated in skin. In SSLs, vitamin E has been identified one main antioxidants that can capture ROS. This paper third part global study evaluates effect radiation on classes consti...
