Microwave-induced combustion coupled to flame furnace atomic absorption spectrometry for determination of cadmium and lead in botanical samples.

A procedure based on microwave-induced combustion coupled to flame furnace (FF) atomic absorption spectrometry (FF-AAS) was used for analysis of solid samples. Botanical samples were prepared as pellets and introduced into a quartz holder device. This device was fitted to a glass chamber that was used for the combustion step.
