On-line electrochemical pre-concentration of arsenic on a gold coated porous carbon electrode for graphite furnace atomic absorption spectrometry

Trace arsenic was pre-concentrated from water samples in a two-electrode electrochemical flow cell coupled on-line to a graphite furnace atomic absorption spectrometer. The cell comprised a microporous electrode made of gold plated porous carbon material with a void volume of about 20 μL. The electrodepositi
