Adsorptive Removal of Heavy Metals and Nutrients from Wastewater
This research community develops materials and methods to remove toxic heavy metals, such as chromium and cadmium, as well as excess nutrients like phosphorus, from water and wastewater streams.
The work centers on designing and testing adsorbents to capture these contaminants from aqueous solutions. Recurring materials include activated carbon, biochar, graphene oxide, and zero-valent iron, often modified or combined into composites for enhanced performance. Specific targets include hexavalent chromium, cadmium, and phosphate ions. The research also frequently employs response surface methodology to optimize removal conditions. Applications focus on wastewater treatment and the remediation of contaminated water, with a strong emphasis on efficient removal rates and the synthesis of low-cost, effective adsorbent materials.
The community is most heavily represented in chromium research, accounting for 38.1% of all tracked chromium papers, with 8,236 papers in this group. It also constitutes a significant share of phosphorus research (7.4%) and cadmium research (4.0%).
The community comprises 36,054 papers, published predominantly in the Journal of Water Process Engineering, Chemical Engineering Journal, and Journal of Hazardous Materials.
Recent work continues to focus on advanced adsorbents, including MOF-based composites for heavy-metal ion adsorption and modified biochar for pollutant removal. Newer studies also explore the simultaneous removal of phosphorus and mitigation of microbial clogging in constructed wetlands, as well as the use of machine learning to model heavy metal adsorption processes.
