Atomic absorption is used to identify metals and metalloids in the environment. This technique is based on the absorption of specific wavelengths of light by ground state metals. A flame or graphite furnace is used to convert dissolved metal ions to their ground states. A detector identifies the wavelengths of light that are absorbed by these ground state metals to determine the concentration of metal ions in an unknown sample.
