          1. Method Overview After appropriate treatment, the sample is injected into a graphite tube atomizer. The cadmium ions contained in the sample are evaporated and dissociated into atomic vapor at high atomization temperature in the graphite tube. The ground-state atoms of the element to be determined absorb the resonance line emitted by the cadmium hollow cathode lamp. Within a certain range, the absorption intensity is proportional to the concentration. 2.
