| titleOfInvention | The measuring method of Cr VI in a kind of plastics |
| abstract | This patent discloses a kind of measuring methods of Cr VI in plastics, under the conditions of ultrasonic extraction, alkaline extracting solution extraction is combined using organic solvent N-Methyl pyrrolidone, solve the problems, such as that hexavalent chromium extraction yield is low in plastics, the rate of recovery that content of 6-valence Cr ions measures in plastics is significantly improved, up to 80~98%；In addition, the sample preparation particle about 2mm × 2mm of this method needs that the cooling of sample liquid nitrogen is first ground into 250 μm of particle < with conventional method, and sexavalence chromium recovery ratio still is below 50% and compares, this method is not only easy to operate, and can really reflect the content of Cr VI in plastics. |
