【 摘 要 】

Polymeric materials are widely used in the chemicalindustry and are part of our daily lives. Inorganic species may be added tothem as additives, anti-oxidizing agents, stabilizers, plasticizers, colorantsand catalysts and may be present in a wide range of concentrations. Their determinationdemands the development of analytical methods considering different kinds ofpolymeric materials, their composition and the final use of the material. Althoughmany different analytical techniques may be used, this review emphasizes thosebased on atomic absorption and emission spectrometry. Solid sampling techniquesand digestion methods are described and discussed and compared considering publishedresults.
