Abstract

bacterial cellulose was prepared in our laboratory by using agriculture wastes. Egyptian bacterial cellulose was isolated from rotten apple. Modification of the prepared bacterial cellulose vis esterification reaction was performed by using succinic anhydride to create active carboxyl groups to be used as ion exchanger. Heavy metal ions such as Cu (II), Zn (II) and Hg (II) ions were used for evaluation the ion exchanger power of the modified bacterial cellulose. The prepared ion exchanger was characterized by using FT-IR spectroscopy and scanning electron microscope (SEM) imaging before and after metal ion absorption. In addition, the absorption and desorption cycles of the ion exchanger were studied. The results shown that the maximum absorption capacity percent of the prepared exchanger for Cu (II), Zn (II) and Hg (II) ions were found to be 81.8, 79.5 and 78.1% respectively.
