Title: Natural ligand for transition metals?
Post by: Cantacoxinha on November 14, 2022, 06:52:35 PM
I'm looking for an organic compound or a class of compounds naturally present in bodies of water (lakes, seas) which might be able to bind transition metals. So far I was able to find only humic acids as an example. Any suggestion on some other compound? Or a good book or a review on types of organic compounds of natural origin in aquatic ecosystems?

The number of compounds is pretty much too numerous to count... but an easy one would be all the various porphyrins

Citrate is a possibility, although it would not surprise me to learn that it is labile to microbial uptake.  Siderophores are likely to be present, as well.
