This standard specifies a general method for the determination of trace amounts of hexavalent chromium in inorganic chemical products using the diphenylcarbazide Spectrophotometric method, spectrophotometry. The method is suitable for the determination of hexavalent chromium Ion concentration in the range of 0.004 mg/L to 1.000 mg/L, with a minimum detection amount of 0.2 μg. This standard provides an accurate detection method for the analysis of hexavalent chromium in inorganic chemical products, which helps to control product mass and environment safety.
