PEMANFAATAN KARBON AKTIF DARI BATUBARA KOTOR (DIRTY COAL) SEBAGAI ADSORBEN ION LOGAM Cd2+ DAN Pb2+ DALAM LARUTAN
Abstrak: The research of
activated carbon utilization of dirty coal as an adsorbent ion cadmium (Cd) and
plumbum (Pb) has been done. In this research, the variations of solutions pH
value (1, 2, 3, 4, 5 and 6), contact time (5, 10, 15, 30, 45, 60, 75 and 90
minutes), and the variation of concentration (20, 40, 60, 80 and 100 mg/L) were
applied. The determination of cadmium and plumbum ion concentraction used an
Atomic Absorption Specthrometer (AAS). The optimum condition cadmium ion on pH
4, than in the plumbum on pH 5 with optimum time contact is 15 minutes and the
maximum adsorptive capacity cadmium ion in value is 2,90 mg/g, than on plumbum
ion is 3,08 mg/g.
