Fly ash-based adsorbent for adsorption of heavy metals and dyes from aqueous solution: a review

Journal of Materials Research and Technology, Journal Year: 2021, Volume and Issue: 14, P. 2751 - 2774

Published: Aug. 9, 2021

A critical global issue in the 21st century is water shortage, as well its pollution with noxious metal ions and organic dyes. To extract these pollutants from wastewater, a variety of traditional methods have been employed but they lack reusability/recyclability, are expensive, environmentally unfriendly, unsafe remediation process takes long time. Therefore, to treat contaminants, nanotechnology (NT) has recently granted several leeways terms making desirable nanomaterials (NMs) high surface-to-volume ratios special surface functionalities. In particular, fly ash (FA) stood out one greatest exciting new-found affordable efficient materials for decontamination owing porosity, huge area, exceptional features. Hence, this present review study will attempt compile data existing literature on utilization FA-based adsorbent removal heavy metals (HMs) dyes wastewater. Based reviewed publications, Langmuir's isotherm models (LIMs) Freundlich's (FIMs) best described sorption thus signalling monolayer multi-layer sorptions. Pseudo-second-order (PSO) model provided appropriate means elucidating kinetic both exothermic endothermic processes revealed nature thermodynamic during sorption. Some recommendations form future prospects how advance capacity adsorption effectiveness FA HMs, other environmental contaminants using innovative technologies such nanofiber technology also proposed.

Plant Extracts Mediated Metal-Based Nanoparticles: Synthesis and Biological Applications

Biomolecules, Journal Year: 2022, Volume and Issue: 12(5), P. 627 - 627

Published: April 24, 2022

The vastness of metal-based nanoparticles has continued to arouse much research interest, which led the extensive search and discovery new materials with varying compositions, synthetic methods, applications. Depending on applications, many methods have been used prepare these materials, found applications in different areas, including biology. However, prominent nature associated toxicity environmental concerns involved most conventional limited their continuous usage due desire for more clean, reliable, eco-friendly, biologically appropriate approaches. Plant-mediated approaches metal emerged circumvent often-associated disadvantages routes, using bioresources that act as a scaffold by effectively reducing stabilizing whilst making them biocompatible biological cells. This capacity plants intrinsically utilize organic processes reorganize inorganic ions into thus studies this area biochemical synthesis analysis. In review, we examined use several plant extracts mediating agent (MNPs). Furthermore, properties, suggested emanate from influence diverse metabolites plants, were also reviewed.
