PEMANFAATAN ARANG AKTIF DARI KULIT DURIAN (Durio zibethinus L.) SEBAGAI ADSORBEN ION LOGAM KADMIUM (II)
Abstrak: The research of
adsorption cadmium (II) metal ions in the solution by activated carbon from
durian peel has been done. Adsorption process is done by using a variation of
pH (1, 2, 3, 4, 5 and 6), variation of contact time (15, 30, 45, 60, 75 dan 90
menit), variation of the concentration (20, 30, 40, 50 dan 60 mg/L). Analysis
of metal ion concentration of cadmium (II) used by Atomic Absorption
Spectrophotometer (AAS). The results of this research shows that the optimum
condition was achieved at the pH value of 4 and the contact time of 60 minutes.
Metal ion adsorption of cadmium (II) by activated carbon from durian’s peel at
pH value of 4 and the contact time of 60 minutes can achieve 64,540%. Metal ion
adsorption capacity of cadmium (II) adsorbed by activated carbon from durian’s
peel can achieve 0,4951 mg/g.
