Abstract
This study examines the sources, hazards, occurrence forms, and removal mechanisms of nitrogen (N) and phosphorus (P) in polluted waters. Furthermore, it critically reviews various studies on adsorbents for removing N/P-containing pollutants from wastewater, such as activated carbon and mineral-based adsorbents. These adsorbents employ various adsorption mechanisms, such as electrostatic attraction and chemisorption. These adsorbents demonstrate efficacy in simultaneously removing nitrate and phosphate from aqueous solutions. Mineral-based adsorbents exhibit high adsorption capacity for N and P pollutants, potentially enabling a "waste for waste" approach. However, developing cost-effective adsorbents is crucial for long-term environmental and economic sustainability. This review offers a novel systematic analysis of adsorbents for N and P removal via co-adsorption. Moreover, this study explores future research directions in advanced purification technologies, adsorbent regeneration, and recycling of spent adsorbents.
期刊介绍：
The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
