1 Scope This Standard specifies a method for determination of nickel in foods with graphite furnace atomic absorption spectrophotometry. This Standard is applicable to the determination of nickel in various foods. Method I: Atomic Absorption Spectrophotometry 2 Principle The samples shall undergo digestive treatment, and then shall be put into the graphite furnace of atomic absorption spectrophotometer; after electrothermal atomization, resonance line at 232.0 nm is absorbed; its absorbance is proportional to nickel content; quantitation shall be conducted by comparing with standard series. As for this method, the detection limit is 1.4 ng/mL and the linearity range is 0 ng/mL~100 ng/mL. 3 Reagent
