This standard specifies the sulfosalicylic acid Spectrophotometric method, spectra-trophotometry and flame atomic absorption spectroscopy (AAS) for the determination of iron content in zinc and zinc alloys, applicable to the determination range of 0.0010% to 0.100%. The standard describes the steps for iron and sulfosalicylic acid to form a yellow complex in ammonia solutions and to measure its Absorbance by spectrophotometer at a wavelength of 430 nm. When the copper content in the solution is too high, the standard recommends the use of an extractant for separation. The standard also lists a detailed list of reagents and instruments to ensure the accuracy and reliability of the measurement results.
