Researchers in Sweden have developed a more eco-friendly way to remove heavy metals, dyes and other pollutants from water. The answer lies in filtering wastewater with a gel material taken from plant cellulose and spiked with small carbon dots produced in a microwave oven.
Reporting in the journal Sustainable Marials and Technologies, researchers from KTH Royal Institute of Technology, in collaboration with Politecnico di Torino, engineered a more sustainable technique for producing hydrogel composites, a type of material that is wteidely studied for wastewater decontamination.
Minna Hakkarainen, who leads the Division of Polymer Technology at KTH Royal Institute of Technology, says that the hydrogels remove contaminants such as heavy metal ions, dyes and other common pollutants….
