The matrix ions at high concentrations have influence on
atomic absorption spectrometric determination of metals at trace
levels [31,34]. The study was performed by analyzing 10 mL of
25 mg L?1 of copper(II)solution containing matrix ions at different
concentrations. The matrix ions listed in Table1 were added to the
model solutions under the optimized conditions and check using
the proposed method.According To The obtained results In Table1,the major ions in real samples have no significant influence on the
determination of copper
