Determination of cadmium in tobacco smoke by

The determination of Cd in ambient air, associated with tobacco smoke, has been carried out by electrostatic precipitation of Cd directly in a graphite tube, which was subsequently used as an atomizer in electrothermal atomization atomic absorption spectroscopy (ET-AAS). It is shown that graphite tube permanently modified with Ir allows carrying out pyrolysis of collected samples at 1000^circC
