The isolation of chitin from shell of shrimps (Cryphios Rosenbergii) has been done through demineralization and deproteination. Chitin was characterized through identification of fimctional groups by FTIR spectrophotometiy, determination of water contents, ash content and deacetylation degree. Chitin was used as adsorbent in adsoption of ion Cd2+ in aqueous water. The result showed that water c…
