Potential biosorbent based on sugarcane bagasse modified with tetraethylenepentamine for removal of eosin Y.

Tetraethylenepentamine (TEPA) modified sugarcane bagasse (SB), a novel biosorbent (TEPA-MSB), was proved to be an effective adsorbent for anionic dyes due to the introduced functional amino groups. FTIR, TG and DSC analysis were employed to characterize the sorbent. The effects of pH, temperature, contact time and initial concentration of dye on the adsorption of eosin Y were investigated.
