Abstract
The removal of Cu(II) chelates of ethylenediaminetetraacetic acid (EDTA) and nitrilotriacetic acid (NTA) from aqueous solutions was studied by batch ultrafiltration (UF) with the help of poly(ethylenimine) (PEI). The Amicon regenerated cellulose YM10 and YM30 were used as ultrafilters. Experiments were performed as a function of aqueous pH, the concentration ratios of chelating agent to Cu(II) ions (α) and of PEI to Cu(II) ions (β), and the applied pressure (ΔP). In general, the removal of Cu−EDTA chelates was more effective compared to that of Cu−NTA chelates. Under the conditions tested (pH 4, ΔP = 2.04 atm, [Cu2+] 0.5 and β > 10 and higher than 96% for Cu−NTA chelates when α > 0.5 and β > 20. The effect of the presence of inorganic salts on the removal was also investigated. Finally, the membrane fouling during UF was analyzed by modified fouling index, and the regeneration of PEI was examined.
