Adsorbent-Based Removal of Heavy Metals and Dyes from Aqueous Wastewater
This community focuses on developing and optimizing materials that capture toxic heavy metals and synthetic dyes from water, primarily to treat industrial wastewater and remediate contaminated aquatic environments.
The research centers on the synthesis and application of adsorbents such as activated carbon, biochar, graphene oxide, and iron oxide nanoparticles. A significant portion of the work involves the removal of hexavalent chromium and cadmium ions from aqueous solutions, often using composite materials like sodium alginate hydrogels or zero-valent iron. Methodologies frequently include response surface methodology for optimizing removal efficiency, while applications extend to wastewater treatment and the elimination of pollutants like methylene blue. The work is driven by the need for efficient, low-cost, and sustainable adsorption processes that can handle complex mixtures of metal ions and organic dyes.
The largest share of the community's output is found in chromium research, accounting for 40.0% of all chromium research tracked, and 7,145 papers here. Cadmium and carbon also appear frequently, with 1,868 and 1,266 papers respectively.
The community comprises 23,767 papers, publishing most frequently in the Journal of Water Process Engineering, Journal of Hazardous Materials, and Chemical Engineering Journal.
Recent work continues to explore advanced adsorbents, including metal-organic framework composites for heavy metal ion adsorption and modified biochar for soil and water applications. Other recent studies examine the use of iron oxide nanoparticles and microalgae-based adsorbents, as well as the application of machine learning models to predict and optimize heavy metal adsorption processes.
