Copper binding by dissolved organic matter: II. Variation in type and source of organic matter
Copper binding properties of several fulvic acid (FA) and whole water samples are compared by means of an empirical model that was calibrated using Suwannee River FA. Within the calibration limits of the model (pH 5.0–8.5, total Cu concentration 0.1–100 μM, ionic strength 0.1, and dissolved organic...

Within the calibration limits of the model (pH 5.0–8.5, total Cu concentration 0.1–100 μM, ionic strength 0.1, and dissolved organic carbon, DOC, 1–10 mg C/1), ρCu in solutions of a variety of FA samples are predicted with
