As(iii) removal through catalytic oxidation and Fe(iii) precipitation

To remove arsenite (As(iii)) from wastewater effectively, the catalytic oxidation of As(iii) to arsenate (As(v)) and As(v) precipitation with iron ions (Fe(iii)) was investigated. The Pt/SiO(2) catalyst functioned as a reaction site for As(iii) with oxygen in the atmosphere. The combination of the P...

Sumario:To remove arsenite (As(iii)) from wastewater effectively, the catalytic oxidation of As(iii) to arsenate (As(v)) and As(v) precipitation with iron ions (Fe(iii)) was investigated. The Pt/SiO(2) catalyst functioned as a reaction site for As(iii) with oxygen in the atmosphere. The combination of the Pt/SiO(2) catalyst and Fe(iii) precipitant improved the removal of As(iii) in the precipitate; Pt/SiO(2) worked as both an As(iii) oxidation site and precipitation site with Fe(iii) precipitant.
