1 Descripción general del 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 Ámbito de aplicación
This method is applicable to the determination of copper in nylon.
