[Comparison of ISE, ASV and FQ for complexation characterization of river water DOC with copper].
Condition stabilization constants of complexation between naturally occurring organic ligand in river water and copper were measured lgk and compared by using ISE, ASV and FQ methods. The measured lgk results were 2.29-6.47 by ISE, 2.61-6.91 by ASV, and 3.52-4.71 by FQ, respectively. The constants went up with the raise of pH, the decrease of copper content, and the increase of ligand concentration.
