2007-4-28  An electrochemical method based on stripping chronopotentiometry (SCP) with a gold film electrode has been developed for determining arsenic in seawater. The detection limits were 0.053 ppb (0.71 nM) and 0.022 ppb (0.29 nM) for total inorganic As (As(T)) and As(III) after deposition times of 60 and 150 s, respectively. Compared to other stripping chronopotentiometric methods that use a gold ...

Treatment of waste seawater by electrolysis using charcoal ...

Dissolved inorganic nitrogen is one of the major sources for eutrophication of lakes and coastal seas. Electrolysis is one of the expected tools for treatment of waste water. If metallic electrodes are used, the metal ions diffuse into water in the prolonged use. It costs too much to use platinum or gold for electrodes, which are difficult to diffuse into water. In the present study, carbon ...
