Adsorption of Heavy Metals and Dyes from Wastewater
This community develops and tests materials that remove toxic heavy metals and synthetic dyes from water, primarily through adsorption processes.
The work centers on designing and synthesizing adsorbents to capture specific pollutants from aqueous solutions. Recurring materials include activated carbon, graphene oxide, carbon nanotubes, and various oxide nanoparticles, often modified into composites. The target contaminants are predominantly hexavalent chromium, lead ions, and other heavy metals, alongside common industrial dyes like methylene blue and congo red. Methods frequently involve the synthesis of porous structures, the application of response surface methodology to optimize removal efficiency, and the evaluation of adsorption kinetics and isotherms. The stated purpose is the efficient removal of these pollutants from wastewater and industrial effluents.
Chromium research accounts for the largest share of this community's output, representing 8.6% of all tracked chromium research, with 9,148 papers in this group. Lead and cadmium also appear frequently, contributing 2.8% and 2.5% of their respective element research totals.
The community comprises 54,717 papers, publishing most heavily in Desalination and Water Treatment, Carbon, and the Journal of Hazardous Materials.
Recent work continues to focus on synthesizing new adsorbents, such as lignin-derived porous carbons and MOF-based composites, for the removal of heavy metals and emerging contaminants. Current studies also explore the use of chitosan derivatives, iron oxide nanoparticles, and machine learning models to optimize adsorption performance and evaluate the sustainability of these materials.
