In this study, adsorption process performance
was assessed using metal oxide nano particles for wastewater treatment
containing heavy metals in a laboratory scale reactor. Copper oxide
nano-particles were prepared and fully characterized considering their
adsorption properties (surface area and pore size distribution) as well as
their chemical structure and morphology.
The adsorption of heavy metals, including Fe3+
and Cd2+ was studied in batch experiments. Various
physico-chemical parameters such as pH, initial metal ion concentration,
and adsorbent dosage level and equilibrium contact time were studied.
The adsorption of Cd2+ and Fe3+ ions increased
with an increase in pH. The optimum solution pH for adsorption of both metals
from aqueous solutions was 6. Adsorption was rapid and occurred within the
first 20 min for both metals within different solution concentrations (250,
100, 50 and 25 mg/L).
