Silalahi, Desiana

The transformation of chitin from snail shell to chitosan and the separation of cellulose acacia mangium wiild has been done. The transformation and separation product was characterized using FT-IR spectroscopy and XRD difractometer. Chitosan and cellulose were modified by impregnation process and then was used to adsorbed Fe (II) from it solution. Interaction time and Fe (H) concentration were…
