| Popis | The inner wall of graphite tube served as the surface for the adsorptive accumulation and for the electrodeposition of gold from the solution. A flow-through cell was constructed. After the deposition step, the graphite tube was placed into the graphite furnace and an atomization programme was applied. As the working electrode served pyrolytic graphite coated tube, uncoated electrographite tube and tube covered by elemental palladium. This palladium surface was achieved by electrodeposition of palladium prior to gold deposition. The procedure with electrodeposition on palladium surface was applied to the determination of gold in river waters. |
