摘要：
The effects of reagent concentration and the pH in the kinetic behavior of the dissociation of Fe(ll)-fulvic acid complexes were studied using a spectrophotometric technique. The results show that this behavior is not strongly affected by the concentration of fulvic acid, the concentration of the metal cation on the ratio of these concentrations and that variations in pH are more important in the dissociation process. A possible explanation based in the relative influence of proton concentration on the stability of the complexes is proposed. (C) 1998 John Wiley & Sons, Inc.
