Abstract:

Synthesis of chitosan with activated carbon from coffee grounds to reduce the metal content of Cadmium (Cd) in standard solutions. Preparation and characterization of activated carbon from coffee grounds have been made. This study consisted of several stages: manufacture of activated carbon from coffee grounds, characterization activated carbon with PSA and FT-IR. Manufacture chitosan with addition variations activated carbon is 0.3 g, 0.4 g, 0.5 g, 0.6 g. The results characterization PSA of activated carbon were 50.72 μm and the activated carbon FT-IR results showed OH group (3487.3 cm-1), CH group (2924.09 cm-1, 2854.65 cm-1), group C = C (1604.77 cm-1), group C = H (1442.75 cm-1, 1381.02 cm-1), CO group (1165.00 cm-1, 1118.71 cm-1) and group C = CH (771.53 cm-1 ). Carbon quality parameters include water content was 4%; ash content was 1,5%; easily evaporated substances was 17,5%; and bound carbon content was 81%. The quality of carbon is appropriate with carbon quality SII No.0258-88. Characterization of chitosan and chitosan - activated carbon from coffee ground by FT-IR shows that there is no difference in wavelength: as for the emerging groups, NH groups (3448.72 cm-1), CH groups (2924.09 cm-1), C = C groups (1635.64 cm-1), C-N group (1381 cm-1), and NH group (3441.01 cm-1).
