GB/T 17593.3-2006 《Textiles―Determination of heavy metals―Part 3: Chromium(VI) ―Spectrophotometry》 Related products

This standard specifies a method for the determination of extractable hexavalent chromium in Spinning & weaving products by Spectrophotometric method, spectra-trophotometry, which is applicable to Spinning & weaving materials and their products. The method is based on the color reaction of diphenylcarbazide after acid sweat extraction, and the absorbance is determined by spectrophotometer at 540nm wavelength to calculate the content of hexavalent chromium in Spinning & weaving products. This standard provides a reliable analytical method for the detection of heavy metals in Spinning & weaving products, which helps to ensure the safety and environmental friendliness of Spinning & weaving products.
