This study investigates, for the first time, the sequential modification of sisal fiber (SF) using hydrogen peroxide (HO), sodium chloride (NaCl), and the cationic surfactant benzyl dimethyl hexadecyl ammonium chloride (HDBAC), enabling the simultaneous removal of reactive black 5 dye (RB5) and lead ions (Pb) from wastewater. Characterization confirmed an increase in carbonyl, carboxyl, and aromatic groups, along with the introduction of quaternary ammonium groups. The HO/NaCl treatment increased the specific surface area by fivefold compared to that of raw SF, whereas subsequent HDBAC modification reduced the total pore volume and specific surface area.
