Summary

Flame atomization of the solutions resulting from treatment of PVC samples with organic solvents is perfectly feasible. In this work, the organic solutions resulting from treatment of PVC with organic solvents are nebulized, after dilution with acetone. This solvent is miscible with those normally used for dissolving PVC, it does not cause precipitation of the polymer and, in general, gives good performance in the flame. The method is applied to the determination of lead and cadmium in real samples of PVC, and the possible interference arising from the PVC resin and from the presence of other metals in the sample is studied.
