This Part of GB/T 39560 specifies the method for quantitative detection of hexavalent chromium [Cr (VI)] in polymer and electronic samples. The determination method in this Part uses an organic solvent to dissolve or swell the sample matrix, and then uses an alkaline digestion procedure to extract hexavalent chromium from the sample. Studies have shown that for the extraction of hexavalent chromium from soluble and insoluble samples, organic/alkaline solutions are more effective than acidic solutions. Under the condition of alkaline solution, the reduction of hexavalent chromium to trivalent chromium or the oxidation of trivalent chromium to hexavalent chromium is the least.
