Synthesis of magnetic Fe3O4/activated carbon prepared from banana peel (BPAC@Fe3O4) and salvia seed (SSAC@Fe3O4) and applications in the adsorption of Basic Blue 41 textile dye from aqueous solutions

Abstract Textile industries use large amounts of water and chemicals for finishing dying processes. The chemical structures dyes vary enormously, some have complicated aromatic that resist degradation in conventional wastewater treatment processes because their stability to sunlight, oxidizing agents, microorganisms. objective this research is compare the adsorption efficiency two types magnetic activated carbons derived from Banana peel Salvia seed removal basic blue 41 dye. faculty produced remove dye aqueous solutions via batch has been examined under several operating conditions such as pH, adsorbent dose, initial adsorbate concentration contact time. cheap, non-toxic (AC) were characterized by scanning electron microscope Brunauer-Emmett-Teller analyses. best with BPAC@ Fe 3 O 4 equal pH = 9, AC dose 0.5 g/L , 50 mg/L equilibrium time 30 min, optimal SSAC@Fe 0.75 min. This study followed Langmuir isotherm model well regression coefficient R 2 0.9886 BPAC@Fe 0.9764 .
