- Method Principle
After appropriate pretreatment, the sample is injected into a graphite tube atomizer. Lead ions are dissociated into atomic vapor at high temperatures within the graphite tube. The ground-state atoms of the target element absorb the resonance line emitted by a lead hollow cathode lamp, and the absorption intensity is proportional to the lead concentration within a certain range, enabling quantitative analysis of lead content.
- Scope
Applicable to the determination of lead in surface water.
