description |
The effects of varying operating conditions on metals removal from aqueous solution using a novel
nano-size composite adsorbent are reported in this paper. Characterization of the composite adsorbent material showed
successful production of carbon nanotubes on granular activated carbon using 1 % nickel as catalyst. In the laboratory
adsorption experiment, initial mixed metals concentration of 2.0 mg/L Cu2+, 1.5 mg/L Pb2+ and 0.8 mg/L Ni2+ were
synthesized based on metals concentration from samples collected from a semiconductor industry effluent. The effects
of operation conditions on metals removal using composite adsorbent were investigated. Experimental conditions
resulting in optimal metals adsorption were observed at pH 5, 1 g/L dosage and 60 min contact time. It was noted that
the percentage of metals removal at the equilibrium condition varied for each metal, with lead recording 99 %, copper
61 % and nickel 20 % , giving metal affinity trend of Pb2+ > Cu2+ > Ni2+ on the adsorbent. Langmuir’s adsorption isotherm
model gave a higher R2 value of 0.93, 0.89 and 0.986 for copper, nickel and lead, respectively, over that of Freundlich
model during the adsorption process of the three metals in matrix solution. |
