Abstract

The potentialities of pseudopolarographic approach regarding trace metal speciation were explored. Recorded pseudopolarogram of a particular metal serves as a fingerprint of the analyzed sample. It gives initial information related to qualitative and quantitative purpose: a first approximation of trace metal distribution with respect to labile and inert metal complexes and the strength of inert metal complexes present in natural sample. Several model electrolyte solutions and natural estuary/seawater samples containing different quantity of Dissolved Natural Organic Matter (DNOM) were used in this study. In addition, Differential Pulse Anodic Stripping Voltammetry (DPASV) measurements were carried out with logarithmic additions to reach information about DNOM complexing capacities and stability constants.
