New Publication: Organic compounds alter the preference and rates of heavy metal adsorption on ferrihydrite, Maya Engle, et al.

Highlights


• Metal binding by Fh followed the order Ni > Zn > Cd.

• Increased metal binding by organic-Fh assemblages followed a reverse order Cd > Zn > Ni.

• Carboxylate functional groups had the greatest impact on metal binding.

• Citric acid, aspartic acid and cysteine-Fh assemblages enhanced metal binding rate.

• Organic groups within the assemblages accounted for up to 60% of Zn binding.
