Adsorbent Materials for Heavy Metal and Dye Removal from Aqueous Solutions
This community develops and tests materials that capture toxic heavy metals and industrial dyes from water and wastewater, using adsorption as the primary separation mechanism.
The research focuses on synthesizing and characterizing adsorbents such as activated carbon, graphene oxide, iron oxide nanoparticles, and sodium alginate composites. These materials are evaluated for their capacity to remove specific contaminants, including hexavalent chromium, lead ions, cadmium, and methylene blue, from aqueous solutions. Methodologies frequently involve response surface methodology for optimizing removal efficiency, while recent work explores magnetic composites, metal-organic framework (MOF) derivatives, and lignin-based porous carbons to enhance selectivity and reusability.
The community is most prominent in carbon research, where it constitutes 1.4% of all tracked carbon papers, and in chromium research, where it represents 4.6% of all tracked chromium papers. It also holds a significant share of lead research at 2.5%.
The community comprises 41,621 papers, published primarily in Desalination and Water Treatment, Journal of Water Process Engineering, and Chemical Engineering Journal.
Recent work continues to focus on advanced adsorbents, including MOF-based composites for heavy metal ions, lignin-derived porous carbons for antibiotic removal, and conductive hydrogels for multi-metal capture, alongside reviews on machine learning applications in adsorption modeling.
