A quick review on the applications of nanomaterials as adsorbents

Abstract

Urbanization and Industrialization have led to release of higher heavy metals amounts into the atmosphere especially aqueous regions. Heavy metals contaminations of potable water have become a serious challenge especially with toxic elements like mercury, lead, zinc, boron and cadmium. Lot of biological constituents has attracted many scientists and researchers due to qualities of cheap and effectiveness for removing heavy metals from waste water. The nanostructured adsorbents exhibit much higher effectiveness and faster rates of adsorption in treatment of water as compared to conservative materials principally because of the remarkably higher surface areas. In the current review, it has been described that the nanomaterials can be used successfully as cost-effective, ecologically friendly, and efficient adsorbents for the elimination of different toxic substances from wastewater.

Deep Learning Methods for Colloidal Silver Nanoparticle Concentration and Size Distribution Determination from UV–Vis Extinction Spectra

“…This and other unique properties of NPs make them exceptionally useful in biomedicine for the detection of antigens, biological warfare agents, and gene delivery . They also found environmental and energy-related applications for cleaning up pollutants in the water and conversion of CO 2 to carbon-based fuels, along with water splitting for the generation of green hydrogen and enhancing solar energy harvesting. , The NP size distribution is one of the most critical parameters for their catalytic efficacy as well as other cellular interactions, especially in cancer detection, and treatment where knowing the NP size distribution is essential. Due to such wide application and the importance of size, simple yet rapid characterization approaches of the NP size distribution information are of special interest in an industrial setting …”
