Water quality - Determination of cadmium by atomic absorption spectrometry (ISO 5961:1994)
Specifies two methods for the determination of cadmium: using atomic absorption spectrometry (AAS) in an air-acetylene flame (aspiration of the acidified sample into the flame and measurement of the cadmium concentration at a wavelength of 228,8 nm) and by electrothermal atomization AAS (injection of the acidified sample into an electrically heated graphite tube of an electrothermal atomization atomic absorption spectrometer and measurement of the absorbance at a wavelength of 228,8 nm).
