title: Elimination of interferences in electrothermal-atomization atomic-absorption spectrometry of cadmium.
abstract: The determination of cadmium by use of a molybdenum-tube atomizer and atomic-absorption spectrometry has been investigated. The absorption profiles for various cadmium compounds and the interferences caused by large amounts of concomitants were evaluated. Sulphur was tested as a matrix modifier for removal of interference and found to be effective at the interferent levels likely to be found in biological samples. A simple, precise and convenient method for determination of cadmium in biological materials has been established.
