- Method Overview
After the sample is dissolved in 2% nitric acid, it is injected into the graphite furnace of an atomic absorption spectrophotometer. After electrothermal atomization, it absorbs the resonance line at 247.6nm. Within a certain concentration range, the absorbance is proportional to the palladium content, and quantification is performed by comparison with the standard series.
