Lignin nanoparticles represent an emerging class of sustainable nanomaterials that can improve the valorisation of this abundant biopolymer through new applications [1 ]. This study focused on optimizing the production of lignin nanoparticles through sonication, using minimal amount of chemicals possible, while achieving small particle size and maintaining colloidal stability.
Textile industry is an economic activity that produces high volumes of effluents used in fabric processing that are discharged in the environment [1]. These discharged effluents loaded with synthetic dyes and other chemicals, are resistant to biodegradation and persistent in water, and are responsible for toxicity and mutagenic effects on the aquatic life, causing a potential risk to the aquatic ecosystems [2]....
