Results revealed that the average arsenic concentration in the studied area was more than the national standard limit, ranging from 11.17 to 2167.98 µg/L. Based on our results, the reverse ...

Biovolatilization is an additional bioprocess able to remove arsenic from surface waters and soils (Jakob et al. 2010; Liu et al. 2011), thus showing a very limited impact on aquifer contamination (Lloyd 2010).Volatile arsenic is formed through a combination of inorganic species reduction and methylation reactions (Rahman et al. 2014).

Arsenic Removal Technologies: A Review. By Mark Reinsel, Apex Engineering. Arsenic is a common element in the earth's crust, natural groundwater, and even the human body. It is an odorless and tasteless semi-metal (metalloid) that is naturally present in aquifers throughout the U.S. and the world. Arsenic is typically found as an …

2.4. Scientometric analysis. The scientometric analysis, a method applied to identify the research priority in any field of science, was applied to identify the research needs in As removal from aqueous solution ( Wu et al., 2020 ). Literature was searched using the keywords "Arsenic", "removal" and "water" in the Scopus.

A key innovation by Galiano et al. is to use a microporous membrane with a pore size of 0.14 μm to selectively pick up soluble arsenic species for their removal 5. It …

Overall, iron-based adsorbents offer significant potential towards developing adsorbents for arsenic removal from water. The recent developments on iron-based adsorbents such as iron oxyhydroxides nanoparticles, zero-valent iron, bimetallic oxides, and iron oxyhydroxide-doped composite materials are fully discussed in this review. Go …

The removal of arsenic from arsenic-bearing minerals is significant for further efficient and clean utilization of mineral resources. Roasting is widely used in industrial production due to its large processing capacity and high efficiency, but it also has the disadvantages of serious pollution and high energy cost.
