Sorption of Arsenic and Heavy Metals Using Various Solid Phase Materials
Woosik Jung, Young Kyu Park, Ju-suk An, Ji Young Park, and Hyun Je Oh
Abstract—A composite adsorbent was synthesized by
immobilizing ferric oxide or three different iron oxides into
alginate beads (HFOAB) for the removal of arsenate [As(V)]
and heavy metals from aqueous phase. Sorption studies were
conducted on single and binary sorbate systems, and the effects
of contact time, initial adsorbate concentration, and pH on
adsorption performance of HFOAB were monitored. The
sorption process for As(V) and Cu(II) reached an equilibrium
state within 240 h and 24 h. The maximum sorption capacity of
As(V) was 13.8 mg g-1 after 168 h. The effect of arsenic species
on Cu(II) sorption was insignificant. The adsorption of As(III),
As(V), and Cu(II) followed pseudo second order kinetics.
Kinetic studies showed that adsorption process reached
equilibrium within 8 h at an initial concentration of 10 mg/L.
Pb(II) and Cd(II) showed a greater sorption capacity on NCBs,
which might be due to sorption sites provided by the
immobilized GNC. The sorption affinity of divalent metal ions
on NCB was in the following order: Pb=Cu=Cd >Zn=Ni>
Co>Mn. The study demonstrates that the synthesized sorbent
could be useful for the simultaneous removal of both anionic and
cationic contaminants from wastewater.
