1 Subject Content and Application Scope This Standard specifies a flame atomic absorption spectrometric method for the determination of the calcium content. This Standard is applicable to the determination of calcium content in cast iron, carbon steel, alloy steel and high temperature alloy. Determination range: 0.0005%~0.010%. 2 Principle The sample is dissolved with hydrochloric acid and nitric acid, add strontium dichloride as interference rejection agent, spray the sample solution into nitrous oxide - acetylene flame, apply calcium hollow cathode lamp as the light source and measure the absorbance at the wavelength 422.7 nm of atomic absorption spectrometer.
