🔬 Discover how our research explores sustainable extraction processes for algal polysaccharides! 🌿 We compared conventional and innovative microwave-assisted methods, focusing on extraction efficiency, yield, and biological activities from Chlorophyta, Rhodophyta, and Phaeophyceae. The microwave method saves time and energy while preserving the polysaccharides' chemical structure, presenting a viable industrial alternative. ♻ By utilizing invasive macroalgal species, we transform waste into valuable resources, promoting environmental sustainability. Our findings open doors to new applications in emulsifiers and bacterial antiadhesives, highlighting the potential of eco-friendly industrial by-products. #Sustainability #Research #AlgalPolysaccharides #MicrowaveExtraction #GreenTechnology #IndustrialBiotechnology

Thrilled to announce the release of my newest article, "Adsorptive removal of anthracene from water by biochar derived amphiphilic carbon dots decorated with chitosan."   Biochar, a porous carbonaceous material produced from biomass pyrolysis, has emerged as a promising solution for adsorbing pollutants from water due to its high surface area and porosity. Studies have shown that biochar effectively adsorbs a wide range of contaminants, including heavy metals, organic pollutants, and nutrients, making it a sustainable and cost-effective option for water remediation. Its ability to sequester pollutants while also enhancing soil fertility highlights its potential for addressing water quality issues while promoting environmental sustainability.  In this paper, carbon dots (CDs) derived from the acid treatment of coconut shell biochar (CDs/MCSB) decorated with chitosan (CS) are successfully synthesized and applied for anthracene removal from aqueous solutions. #Biochar #Watertreatment #Adsorption #SustainableTechnology #GreenChemistry 

#Eutrophication, a major environmental concern, demands efficient phosphorus and ammonium removal. A new study explores promising “greener” solutions using magnesium-based #biochar composites (MBCs). The researchers employed #ultrasonic cavitation to create more adsorption sites on MBCs, significantly improving their capacity to capture nutrients and their suitability for green #recycling. https://lnkd.in/dTWB2FeY

Researchers developed a ZnO/ACSC@TiO2 composite using coconut shell #biochar, TiO2, and ZnO. This photocatalyst efficiently removes organic pollutants like #tetracycline and #RhodamineB from #wastewater via enhanced adsorption and photocatalysis, achieving up to 99.4% removal efficiency under visible light irradiation. https://lnkd.in/gJJh95dw

🚨 Perfluamine Proposed as a Substance of Very High Concern (SVHC) 🚨 Belgium has proposed listing Perfluamine (CAS Number: 338-83-0) as a Substance of Very High Concern under the EU's REACH Regulation due to its environmental risks. Perfluamine is widely used in various industries: 🔬 Heat Transfer Fluid: Ideal for high-temperature applications. ⚗ Solvent: Used in chemical reactions requiring stability. 💡 Electronics: Provides cooling and insulation due to its non-conductive nature. 🏭 Fluoropolymer Manufacturing: Adds stability and resistance to harsh environments. Risks Associated with Perfluamine: 🌿 Environmental Persistence: Highly resistant to degradation, with an atmospheric lifetime of up to 3,795 years. 🐬 Bioaccumulation: Can build up in living organisms, posing long-term ecological and health risks. Next Steps: The European Chemicals Agency (ECHA) has opened a public consultation period. Stakeholders, including industry representatives, environmental organisations, and the public, are encouraged to submit their comments by 14 October 2024. #Perfluamine #EnvironmentalSafety #ChemicalRegulation #REACH #Sustainability #ECHA #PFAS

The escalating concern over #heavymetal #pollution in #China necessitates innovative solutions for effective remediation. This study explores the promising synergy between biochar and organic phosphorus-degrading bacteria (OPB3–6–1) for heavy metal adsorption, utilizing #walnut green husk #biochar as the carrier. Loaded with OPB3–6–1, biochar (IOPB) demonstrated a remarkable synergistic effect. https://lnkd.in/gtBXENGe

Source: Membranes RO and NF technologies face fouling issues, particularly from LMWOCs due to dwindling water quality. Organic foulants like NOM and EfOM are challenging, with LMWOCs (surfactants, phenolics) causing significant fouling. This review explores LMWOC interactions with membranes, highlighting surface and internal fouling mechanisms. Correlation between fouling and octanol-water partition coefficient is noted. Part 2 will address countermeasures and LMWOC applications.
