Adsorption of Mercury(II) by Iron Hydrous Oxide Gel1

  1. D. G. Kinniburgh and
  2. M. L. Jackson2



Freshly prepared iron hydrous oxide gel suspensions, 0.093M and 0.001M with respect to Fe, strongly adsorb Hg(II) from solutions containing 2.5 × 10−5M Hg(II) and 1.0 × 10−6M Hg(II), respectively. The pH at which 50% of the total adsorption occurred in the latter system is 4.3. In the presence of chloride (Cl/Hg(II) mole ratio of 4/1), the adsorption of Hg(II) is considerably reduced, with no significant coadsorption of 36Cl, indicating that Hg(II)-Cl complexes are not adsorbed by Fe gel.
