Advanced oxidation procedures (AOPs) refer to a variety of technical procedures that
produce OH radicals to sufficiently oxidize wastewater, organic pollutant streams, and toxic …

The occurrence of new emerging contaminants in surface waters has recently grabbed
increased attention of the scientific community. The adoption of Advanced Oxidation …

The exposure to low or high concentrations of arsenic (As), either due to the direct
consumption of As contaminated drinking water, or indirectly through daily intake of As …

In this work, direct Z-Scheme photocatalyst (ZnFe 2 O 4/gC 3 N 4) was employed to purify Cr
(VI) and As (III) in wastewater. Results showed that Cr (VI) and As (III) was completely …

This paper reviews the current knowledge on the toxicity, speciation and biogeochemistry of
arsenic in aquatic environmental systems. The toxicity of arsenic is highly dependent on the …

Arsenic contaminations of groundwater in several parts of the world are the results of natural
and/or anthropogenic sources, and have a large impact on human health. Millions of people …

Considering the toxic effects of arsenic, the World Health Organization recommends a
maximum concentration of 10 μg L− 1 of arsenic in drinking water. Latin American …

This study evaluated the effectiveness of nanocrystalline titanium dioxide (TiO2) in removing
arsenate [As (V)] and arsenite [As (III)] and in photocatalytic oxidation of As (III). Batch …

Contamination of terrestrial and aquatic ecosystems by arsenic (As) is a very sensitive
environmental issue due to its adverse impact on human health. Although not anthropogenic …

Arsenic contamination has been found in the groundwater of several countries.
Photocatalysis can rapidly oxidize arsenite (As (III)) to less labile and less toxic arsenate (As …
