The Direct Blue 71 (DB71) dye can pose risks to the life of aquatic flora, fauna, and human beings, owing to its toxic, carcinogenic, and mutagenic nature. Hence, this study fabricated and applied acid-activated shrimp shell-derived hydrochar (A-WSH) for the adsorptive removal of anionic DB71 from a...
