The role of nanomaterials as effective adsorbents and their applications in wastewater treatment

Abstract: Nanomaterials have been extensively studied for heavy metal ions and dye removals from wastewater. This article reviews the role of nanomaterials as effective adsorbents for wastewater purification. In recent years, numerous novel nanomaterial adsorbents have been developed for enhancing the efficiency and adsorption capacities of removing contaminants from wastewater. The innovation, forthcoming development, and challenges of cost-effective and environmentally acceptable nanomaterials for water purification are discussed and reviewed in this article. This review concludes that nanomaterials have many unique morphological and structural properties that qualify them to be used as effective adsorbents to solve several environmental problems.

Pseudo-second-order kinetic equations for modeling adsorption systems for removal of lead ions using multi-walled carbon nanotube

Abstract: This study investigated the lead ion removal of the multi-walled carbon nanotubes (MWCNTs) and oxidized multi-walled carbon nanotubes (MWCNT-COOH). The main purpose of this work is to study the possibilities on the removal of Pb(II) ions from aqueous solutions using MWCNTs and MWCNT-COOH surfaces as adsorbents. Removal of Pb(II) ions was investigated using solutions with different concentrations in the range 10 to 100 mg/L. In this study, removal of Pb(II) ions on surfaces has been investigated by atomic absorption spectrophotometry. The microstructure of carbon nanotubes were characterized using scanning electron microscopy. Three different kinetic theories were applied to experimental data. The kinetic rates were modeled using the pseudo-first-order, four-type linear pseudo-second-order, and intraparticle diffusion. The pseudo-second-order model was found to explain the adsorption kinetics most effectively. The results indicated a significant potential of the multi-walled carbon nanotube as an adsorbent for Pb(II) ion removal.

Green synthesis of silver nanoparticles using the plant extract of Salvia spinosa grown in vitro and their antibacterial activity assessment

Abstract: Researchers use bionanotechnology techniques as eco-friendly and cost-effective routes to fabricate nanoparticles and nanomaterials. The present study confirms the ability of plant extract of Salvia spinosa grown under in vitro condition for the biosynthesis of silver nanoparticles (Ag NPs) for the first time. The surface plasmon resonance found at 450 nm confirmed the formation of Ag NPs. Moreover, FESEM images showed that nanoparticles had spherical morphology. Furthermore, XRD analysis confirmed the crystalline nature of the particles. FTIR analysis was carried out to identify possible biomolecules responsible in bioreduction of silver ions. Antimicrobial assay verified bactericidal activity of biosynthesized Ag NPs against Gram-positive and Gram-negative bacteria. According to the results, by growing the plants under controlled conditions, it is feasible to synthesize nanoparticles with desired properties.
