- Scope
- After the grain sample is introduced into the electric evaporator, the sample is heated under air flow to remove moisture and organic matter. The cadmium released from the pyrolysis sample in the nitrogen-hydrogen mixture is sent to the hydrogen flame for atomization. The cadmium atoms absorb the 228.8nm characteristic line, and at a certain Within the concentration range, the absorption intensity is proportional to the concentration of cadmium and is quantified by the external standard method.
