Adsorbent-Based Removal of Heavy Metals and Dyes from Water
This community develops materials and methods to remove heavy metals, dyes, and other pollutants from water and wastewater.
The work centers on the synthesis and application of adsorbents, with a strong focus on activated carbon, biochar, graphene oxide, and iron-based composites. Recurring applications include the removal of hexavalent chromium, lead, arsenic, and methylene blue from aqueous solutions. Methods frequently involve the modification of natural materials, such as sodium alginate and chitosan, to enhance their capacity for binding metal ions. The research also explores the use of zero-valent iron and magnetic nanoparticles to facilitate the separation of contaminants. Optimization of these processes often relies on response surface methodology to determine the most efficient conditions for pollutant removal.
The community is most heavily represented in research tracked for Chromium, accounting for 15.8% of all Chromium research and comprising 7,904 papers. It also constitutes a significant share of Arsenic research (6.3%) and Carbon research (4.0%).
There are 61,321 papers in this community, with the highest volume published in the Journal of Water Process Engineering, Journal of Hazardous Materials, and Chemical Engineering Journal.
Recent work continues to focus on the development of novel adsorbents, including MOF-based composites and modified biochars, for the removal of heavy metals and emerging contaminants. There is also ongoing research into the reusability of spent adsorbents and the application of machine learning to model adsorption processes.
