1 Resumo do Método
After sample digestion, the sample is atomized by flame, and the absorbance is measured at 324.8 nm. Within a certain concentration range, the absorbance of copper is proportional to its content, and quantification is performed by comparison with the standard series.
2. Âmbito de aplicação
This method is applicable to the determination of copper in nylon.
