1 Method Overview
After pretreatment, the sample solution is introduced into the atomic absorption spectrophotometer for flame atomization, and the absorbance is measured. Within a certain concentration range, absorbance is proportional to nickel content, and quantification is performed by comparison with a standard series.
2 Scope of Application
This method applies to the determination of nickel in the reflective coating of mirrors.
