Abstract

Exposure to arsenic (As), even at trace level, is believed to be a risk for human health and ecological systems. Thus, how to effectively and deeply remove arsenic from water systems is a very important but still challenging task for environmental researchers. A great variety of water treatment methodologies such as precipitation, oxidation, membrane processes, surface complexation or selective adsorption have been studied for significant reduction or remove arsenic from contaminated effluents. The use of nanomaterials as adsorbent materials for environmental remediation has a great potential due to their physical and chemical properties. This work aims to provide greater depth of understand of the successful integration of nanoadsorbents in water treatment technologies and give new insights into future research directions for the implementation of the nanotechnologies in a near future.
