Preparation and Characterization of Chitosan with Activated Carbon as Adsorbent to Reduce Level Metal Cadmium (Cd) and Nickel (Ni)

Preparation and characterization of chitosan with activated carbon have been made with the aim of reducing the metal content of Cadmium (Cd) and Nickel (Ni) in standard solutions. Characterization chitosan with activated carbon by FT-IR, SEM, and test adsorption by using AAS. Characterization of chitosan and chitosan activated carbon by FT-IR shows that there is no difference in wavelength: as for the emerging groups, NH groups (3448.72 cm), CH groups (2924.09 cm), C = C groups (1635.64 cm), C-N group (1381 cm), and NH group (3441.01 cm). SEM characterization on chitosan activated carbon shows a rude surface. Absorptions of Cd and Ni in chitosan that best with addition carbon of 0.6 g that is 74.54%
