Nano-fibrillated bacterial cellulose (NFBC) has very long fibers (>17 μm) with diameters of approximately 20 nm. Hence, they have a high aspect ratio and surface area. The specific area NFBC can potentially be utilized as an adsorbent. However, no functional groups that bind metal ions, limiting its potential applications. In this study, the hydroxyl on were chemically modified EDTA monoanhydride to convert into fiber morphology crystal structures almost identical those unmodified NFBC, suggesting well-conjugated groups. Surface-modified preferentially adsorbed transition metals in aqueous solutions, such Cu(II), Hg(II), Pb(II), Cd(II), but hardly Mg(II) Cr(VI). adsorption heavy ions explained by pseudo-second-order kinetics chemisorption process Langmuir isotherm model. Furthermore, EDTA-modified is renewable recyclable results study indicate surface-modified biosorbent for removal chemical, food, pharmaceutical, other industrial fields.
