Can you get redox potential from dissolved oxygen in water?

Hi there,

I am trying to get the Eh (or pe) of water samples which I took last summer. I didn't measure it directly at the time. I do have dissolved oxygen values from each site. Is there a way to convert dO2 into Eh? All the dO2 values were in the 80-100% range.

Alternatively, is there a way to convert dO2 into oxygen fugacity?

I am hoping to make phase diagrams for the speciation of dissolved metals in a river.

Thanks!

Sounds like you should use Nernst equation.
