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.
