The GB/T 223.54-1987 specifies the process for the determination of nickel in steel and alloys by flame Atomic absirption spectrophography-tometry, AAS. It is based on the principle of nickel absorption of specific wavelengths of light, and details the required instrumentation and equipment, including the accuracy of atomic absorption spectrophotometer. It specifies the preparation of sample collection, processing and dissolve, and specifies the test operation steps such as instrument debugging and measurement wavelength selection. According to this standard, the nickel content in steel and alloys can be accurately determined, providing key data basis for quality control and performance evaluation of steel and alloy products.
