I'm searching for a natural compound or a class of mixtures normally present in waterways (lakes, oceans) which could possibly tie progress metals. Up until this point I had the option to track down just humic acids for instance. Any idea on another compound?

What is a "progress metal"? Perhaps you are using a translator and it has not chosen a good term.

I bet "transition metal" is a better phrase.

Yes I was wondering about that, but decided it would be better not to lead the witness. 😉 

Thanks All of You for your opinions
