GB/T 28019-2011 《Adornment - Determination of Chromium（Ⅵ）- 1, 5-Diphenylcarbohydrazide spectrophotometric method》 Related products
This standard specifies a method for the determination of hexavalent chromium in jewelry by the Spectrophotometric method, spectrophotometry method of diphenylcarbazide. The method leaches water-soluble and non-water-soluble hexavalent chromium compounds, reacts with diphenylcarbazide to form a purplish-red complex, and uses the Spectrophotometric method, spectrophotometry to determine at 540nm. The standard is applicable to the detection of hexavalent chromium in various types of jewelry to ensure that the product meets safety and environmental protection requirements.
