摘要

Abstract

The anodic stripping voltammetry with physically-coating mercury film electrode was used to investigate the complexing action of trace heavy metals in seawater with organic ligands. The apparent copper complexing capacity of seawater was determined by titrating the organic ligands in natural seawater with standard ionic copper solution. The complexing actions of copper in seawater with humic acid (HA) or fulvic acid (FA) were investigated by titrating copper in seawater with HA or FA solution. The equilibrium time

electrodeposition potential

and effect of pH etc. were investigated respectively. The results show that the interaction of copper in seawater with organic matter is a fast process. At natural pH

HA or FA tend to act with copper in seawater to form nonlabile complexes. During experimental electrode process

these complexes did not significantly dissociate. The experimental results were calculated according to 1∶1 complex formation.
