Abstract
Arsenic (As) is a toxic metalloid risking the health of millions of people globally due to drinking of As-contaminated water or through ingestion of As-contaminated food crops. Although numerous conventional techniques have been introduced to remove As from drinking water and wastewater, sorption is considered one of the most promising approach. Here, we provided emphasis on the potential of nano-enabled As remediation using various nanomaterials (e.g., nano- zero valent iron (nZVI), carbon nanotubes (CNTs), and nano-biomaterial based nanocomposites) for the removal of As from water. In this chapter, advancements in research on nano-enabled technologies are elucidated that has been used for removal of As from contaminated water. The utilization of raw and engineered nanoparticles (NPs) such as CNPs, graphene-based NPs, copper oxide, titanium oxide-based NPs, and bi-metal oxide-based NPs has also been discussed. Also, different techniques for the physicochemical characterization of NPs, including XRD, XPS, SEM, FTIR spectroscopy have been briefly explained for better understanding of the mechanisms for As removal. Moreover, some key parameters that influence on As adsorption capacity of NPs such as pH, particle size, initial As concentration and competing ions.
