Selective Nickel Leaching from Cu-Ni Sulfide Ores Using Deep Eutectic Solvents

Traditional hydrometallurgical lixiviants such as sulfuric and hydrochloric acid pose environmental and safety risks due to their corrosive and toxic nature. To advance greener extraction technologies, this study evaluated deep eutectic solvents (DESs) as potential sustainable al...

From Invasion to Innovation: Synthesis and Characterization of Carboxylated Cellulose Nanocrystals from Prosopis Cellulose and Its Evaluation for Copper(II) Removal from Aqueous Solutions

Abstract Prosopis species (mesquite) was used as a lignocellulosic feedstock for producing carboxylated cellulose nanocrystals (CNC) through the ammonium persulfate (APS) oxidation method. The percentage yields of extracted cellulose and CNC were determined to be 40.40 ± 1.23% an...
