Arsenic contamination, caused by human activities, is a severe form of environmental pollution. Authorities worldwide are focusing on decontamination techniques due to the harmful effects of even low levels of arsenic in drinking water. This review covers well-established and cutting-edge technologies, such as ion exchanges, adsorption, membrane processes, electrokinetic processes, electrocoagulation, precipitation, phytoremediation, inexpensive methods, emerging techniques, nanoparticles, and nano based adsorbents, which can effectively remove arsenic impurities from drinking water. While adsorption techniques gain global attention due to their low cost and simplicity, nanotechnology is believed to be essential in providing clean, inexpensive water to meet human needs.
Arsenic (As) contamination is one of the most serious forms of environmental pollution caused by human activities. Numerous concerned authorities around the world are now focusing on the As decontamination. The technologies for removing As have grown in importance since it is understood that even very low amounts of As in drinking water can have serious negative effects on health. This review provides a thorough explanation of the various well-established and cutting-edge technologies, including ion exchanges, adsorption, membrane process, electrokinetic processes, electrocoagulation, precipitation, phytoremediation, inexpensive useful methods, emerging remedial techniques, nanoparticles and nano based adsorbents that can be used to remove As impurities from the drinking water. The low cost, simplicity and easy operational mechanism of adsorption technique gained much attention globally, however, it is also believed that nanotechnology will be essential in supplying clean, inexpensive water to suit human needs.
