If pure HCl acid is used, the term [P.sub.[beta]] is given as a function of Ferrous (
FeII) and Ferric (FeIII) ion concentration ([I.sub.2] and [I.sub.3] , respectively) in ppm as follows:
At that time, without oxygen, the world was full of sulfide, or hydrogen sulfide, metallic iron, dissolved iron in the
FeII state, and all the saturated hydrocarbons that had been formed since the beginning of life under reducing conditions.
Treatment A (20 mM [H.sub.2][O.sub.2], 0.142 MPa) and B (5 mM
FeII: 20 mM [H.sub.2][O.sub.2], 0.257 MPa) showed no significant difference from each other.
Discovering a happy overlap between Valley-speak and art history, Delia Brown copped hers from Gauguin, no less, who called a painting of 1892 Aha oe
feii?, a phrase he translated "What, are you jealous?" as part of a yarn about the good life in Tahiti.
The results are reported as
FeII equivalents per mg protein.
