GB/T 22807-2019 《Leather and fur—Chemical tests—Determination of chromium(VI) content:Colorimetric method》 Related products

GB/T 22807-2019 focuses on the chemical test of leather and fur, and determines the content of hexavalent chromium by Spectrophotometric method, spectrophotometry. The standard clarifies the determination principle, specifies the required reagents, instruments and equipment, specifies the operation process, covers sample preparation, detection steps and other links, and standardizes the calculation and representation of results. Spectrophotometric method, spectrophotometry has the characteristics of easy operation and relatively accurate results. Through this standard, it can effectively monitor the content of hexavalent chromium in leather and fur products, help the industry mass control, and ensure product safety and environmental friendliness.
