Technologies for Arsenic Removal from Water: Current Status and Future Perspectives

Nina Ricci Nicomel et al. Int J Environ Res Public Health. .

Abstract

This review paper presents an overview of the available technologies used nowadays for the removal of arsenic species from water. Conventionally applied techniques to remove arsenic species include oxidation, coagulation-flocculation, and membrane techniques. Besides, progress has recently been made on the utility of various nanoparticles for the remediation of contaminated water. A critical analysis of the most widely investigated nanoparticles is presented and promising future research on novel porous materials, such as metal organic frameworks, is suggested.

Keywords: adsorption; arsenic; engineered nanoparticles; metal organic framework; pollution; water purification technology.

More oxic conditions, e.g., surface waters, stimulate the formation of arsenate. Moreover, the threshold potential required to form arsenate is lowered at high pH.
