Figure 6
A plot of E'1/2 from pseudovoltammograms vs. log Ktherm for Zn-organic complexes dissolved in seawater. 1 = oxalic acid; 2 = CTP; 3 = ethylenediamine; 4 = glycine; 5 = 8-hydroxyquinoline; 6 = iminobis(metnylenephosphonic acid); 7 = EDDA; 8 = NTA as Zn(NTA)2. The numbers 9–11 refer to unknown complexes in Delaware Bay waters (see Fig. 7).
