“…Arsenic is most effectively removed or stabilized when it is present in the arsenate form (Jekel 1994). The technologies for arsenic removal usually include the following processes: coagulation-filtration (Khan et al 2002;Wickramasinghe et al 2004;Bilici Baskan and Pala 2010;Mólgora et al 2013), membrane separation (Ning 2002;Shih 2005;Pal et al 2014), ion exchange (Flicklin 1983;Katsoyiannis and Zouboulis 2002;Tresintsi et al 2014), and adsorption (Lin and Wu 2001;Zeng 2003;Chammui et al 2014). Among these methods, adsorption offers many advantages including simple and stable operation, easy handling of waste, absence of added reagents, compact facilities, and generally lower operation cost (Akin et al 2012).…”

Contamination of natural waters with arsenic, which is both toxic and carcinogenic, is widespread. Among various technologies that have been employed for arsenic removal from water, such as coagulation, filtration, membrane separation, ion exchange, etc., adsorption offers many advantages including simple and stable operation, easy handling of waste, absence of added reagents, compact facilities, and generally lower operation cost, but the need for technological innovation for water purification is gaining attention worldwide. Nanotechnology is considered to play a crucial role in providing clean and affordable water to meet human demands. This review presents an overview of nanoparticles and nanobased adsorbents and its efficiencies in arsenic removal from water. The paper highlights the application of nanomaterials and their properties, mechanisms, and advantages over conventional adsorbents for arsenic removal from contaminated water.

“…In wastewater treatment, treatment processes for toxic metal-contaminated water have received much interest in recent years in order to comply with stringent regulations, which are caused by direct contamination in water and indirect the subsoil mobility of ions (Kurniawan et al, 2006, Domergue andVédy, 1992). Due to the requirement of discharge concentrations for heavy metal ions to be at ppb levels, dilute heavy metal ion removal processes, such as chemical precipitation (Charerntanyarak, 1999;Mólgora et al, 2013), ion exchange (Inglezakis et al, 2005), adsorption (Najafi et al, 2012), biosorption (Ajjabi and Chouba, 2009) and membrane filtration (Hafiane et al, 2000;Hankins et al, 2005, Hankins et al, 2006, have been widely researched. Specifically, the uses of surfactant and polymer systems have each been individually investigated for their abilities to remove heavy metal ions from aqueous solutions with the aid of ultrafiltration (Cañizares et al, 2008, Fillipi et al, 1999.…”
