Determination of Metals in Paint and Vinyl Additives by Atomic Absorption Spectrophotometry

A method is described for determining the metal content of paint and vinyl additives by atomic absorption spectrophotometry. The chief advantage of this technique is the ability to analyze multielement metallo-organic compounds and complex mixtures without prior chemical separation at a considerable savings in time, compared to wet chemical methods. Accuracy of better than 1% relative error, and precision equivalent to wet chemical analysis were obtained.
