Scientists have developed a new method that removes toxic pollutants from wastewater. <\/p>\n
Developed by researchers from Dalhousie University, the innovative method offers a new way to reuse wastewater sustainably.<\/p>\n
The simple and eco-friendly method to turn agricultural and forestry waste into powerful magnetic materials can effectively remove toxic chemicals from water.<\/p>\n
Sustainable, low-cost, and reusable solution<\/p>\n
\u201cOur goal was to develop a sustainable, low-cost, and reusable solution for treating wastewater contaminated with harmful chemicals,\u201d said lead author Tunnisha Dasgupta, a researcher at Dalhousie University\u2019s Faculty of Agriculture.<\/p>\n
\u201cBy using agricultural and forestry residues, we are not only cleaning water but also giving new value to waste materials.\u201d<\/p>\n
Researchers demonstrated magnetic carbon adsorbents made from two common waste products: flax shives and eucalyptus sawdust.<\/p>\n
Method turns biomass into carbon-rich solids<\/p>\n
These materials were converted into \u201chydrochar\u201d through a process called hydrothermal carbonization, which transforms biomass into carbon-rich solids under heat and pressure. By adding iron during the process, the researchers created magnetic hydrochars that can be easily separated from treated water using a magnet, eliminating the need for costly filtration, according to a press release.<\/p>\n
Published in Sustainable Carbon Materials, the study involves converting biomass waste into magnetic carbon-based adsorbents through hydrothermal carbonization (HTC).<\/p>\n
The research team revealed that during the HTC process, iron was incorporated to impart magnetic properties to the resulting hydrochar, enabling post-treatment recovery using an external magnet. Hydrochars derived from flax shives (FS-Fe-HC), and eucalyptus (ES-Fe-HC) were tested for their efficiency in adsorbing pentachlorophenol (PCP) from
wastewater.<\/p>\n
\u201cThis study demonstrates the potential of HTC as a sustainable approach for valorizing lignocellulosic waste into effective bio-adsorbents for wastewater remediation, addressing both environmental and industrial challenges,\u201d said researchers.<\/p>\n
\u201cThe novelty lies in utilizing dual biomass waste, magnetic recovery capability, and high reusability with minimal iron leaching, thereby contributing to circular economy practices in water treatment.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Scientists have developed a new method that removes toxic pollutants from wastewater.
