1 Method Summary
The sample is digested by microwave digestion. Atomic fluorescence is generated under excitation by a high-intensity cadmium hollow cathode lamp. The fluorescence intensity is proportional to the cadmium concentration under fixed conditions. Quantification is performed by comparison with the standard series.
2 Scope
Applicable to the determination of cadmium in nettle leaves.
