1 Yöntem Genel Bakış
After microwave digestion, the sample solution is injected into the graphite furnace of the atomic absorption spectrophotometer. Following electrothermal atomization, it absorbs the resonance line at 283.3 nm. Within a certain concentration range, the absorbance is proportional to the lead content, and quantification is performed by comparison with the standard series.
2. Uygulama Kapsamı
This method is applicable to the determination of lead in graphite powder.
