| Abstract: | -- The complexation
capacity for heavy metals (Cu, Cd, Pb) were determined by anodic stripping voltammetry in
South China Sea, Hulun Lake and Wuliang Suhai. The conditional stability constants and
complexation capacity index were calculated. The data showed that the complexation
capacity of the Hulun Lake was greater than that of seawater and Wuliang Suhai. The
sequence of complexation capacity is C (CuL) > C (CdL) > C (PbL), the values are in
concord with results of analysis on dissolved organic carbon. The conditional stability
constants were in an opposite sequence K (CuL) < K(CdL) < K (PbL). When logK are
similar, the greater the complexation capacity, the greater the complexation capacity
index. |
