摘要：
The complexation capacity of both model systems and natural waters was investigated by anodic shipping voltammetry (ASV) employing copper as the titrating ion. EDTA, NTA, citrate and humic acids were employed as model systems. Natural waters from the Santiago River were also investigated. In some cases the influence of the electrode rotating speed on the lability of the species involved was investigated. The experimental results were analyzed employing diagnosis criteria proposed by previous workers for lability, complex strength and stability constants.
