Summary: In this study, Hydrilla verticillata biomass was used to remove Reactive Red 120 dye from simulated wastewater. The research found that Freundlich's isotherm and pseudo-second-order equation were good fits for describing the sorption of RR120 dye. Optimal conditions for maximum removal of the dye were determined through experimental studies, with adsorption occurring through an endothermic process.
