Sorption of Arsenic and Heavy Metals Using Various Solid Phase Materials

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.
