| Abstract: | To determine trace copper and lead and cadmium in water by using the method of Graphite Furnace Atomic Absorption spectrophotometry in the paper. By selecting adaptive apparatus condition and rising temperature program condition as well as paying attention to adjust the auto-sampler capillary trip position and select type of graphite tube, the result indicates that the definition and veracity is good, the sensitivity is high and can reach the requirement of determination of trace copper and lead and cadmium in water. |
