    1. Method Overview After the sample is digested, its absorbance is measured at a wavelength of 357.9 nm via graphite furnace atomization. Within a certain concentration range, the absorbance of chromium is proportional to its content. Quantitative determination is conducted by comparing with a standard series. 2.
