Copper binding by dissolved organic matter: I. Suwannee River fulvic acid equilibria

A cupric ion-selective electrode measured free Cu in solutions of Suwannee River fulvic acid (FA) in a series of 30 titrations carried out both at variable and at constant (5.14, 7.00, 8.44) pH. Total Cu varied 0.1–100 μM, dissolved organic carbon (DOC) 1–10 mg C/l, Ca and Mg 0–10 mM, and ionic stre...
