Abstract :
Increasing the pollution rate of water sources is one of the most severe issues that the world faces.
This issue has stimulated researchers to investigate different treatment methods such as adsorption,
chemical precipitation, membrane filtration, flocculation, ion exchange, flotation, and electrochemical
processes. Among them, adsorption has gained broad interest due to its ease of operation, low cost, and
high efficiency. The critical factor of the successful adsorption treatment process is finding attractive
adsorbents with attractive criteria such as low cost and high adsorption capacity. In the last few decades,
nanotechnology has attracted much attention, and numerous nanomaterials have been synthesized for
water and wastewater treatment. This work provides a quick overview of nanomaterials, which have
been investigated for water remediation as adsorbent and photocatalyst. This work reviewed 120 articles
to provide a critical review to determine the limitation of using nanomaterials in water treatment at the
commercial scale.
