Lignocellulose hydrogel warms to removing pollutants
“The total amount of water on Earth doesn’t change with time, but demand does,” said Minna Hakkarainen, who leads the Division of Polymer Technology at KTH. “These all-lignocellulose hydrogels offer a promising, sustainable solution to help ensure access to clean water.” The hydrogel composites can be made from 100 per cent lignocellulose, or plant matter – the most abundant bioresource on Earth, she said in a statement. One ingredient is cellulose gum (carboxymethyl cellulose, or CMC), a thickener and emulsion commonly derived from wood pulp or cotton processing by-products and u...
