ClearAdsorptive removal of heavy metals from wastewater using Cobalt-diphenylamine (Co-DPA) complex
Researchers synthesized a new cobalt-diphenylamine complex and tested it for removing heavy metals like cadmium, lead, and chromium from wastewater. The material showed strong adsorption capacity, with removal efficiency influenced by factors such as pH, dosage, and initial metal concentration. The study suggests this type of metal-organic complex could be an effective tool for treating industrial wastewater contaminated with heavy metals.
Polymer-based nanocomposite adsorbents for resource recovery from wastewater
This review evaluates polymer-based nanocomposite adsorbents for recovering nutrients like phosphorus and nitrogen from wastewater, highlighting their high surface area, multiple functional groups, and biodegradability as advantages over conventional adsorbents, with recovered nutrients applicable as soil amendments.
Textile Waste Recycling: Emerging Technologies, Environmental Challenges, and Sustainable Solutions
This review synthesizes current knowledge on textile waste recycling, covering mechanical, chemical, and biological recycling technologies alongside environmental challenges and sustainability trade-offs. The authors highlight microfiber shedding and hazardous dye contamination as key barriers to effective textile circularity, and identify emerging solutions including enzymatic processing and closed-loop fiber-to-fiber recycling.
