Abstract

The invention provides a method for detecting the chromium element in jelly. Cr (III) is an essential trace element in human bodies, but hexavalent chromium Cr (VI) has obvious toxicity to human bodies, has a stimulating and corroding effect on skin mucosa, interferes important enzyme systems, and has carcinogenesis and gene mutation induction effects. The method for detecting the chromium element in jelly comprises the following steps: drawing a standard curve; preparing and preprocessing a sample; preparing an internal standard solution, and selecting a tuned liquid; producing an ion exchange column, and regenerating and filling resin; and detecting the practical sample. The method has the advantages of low lower detection limit, high precision and high sample analysis ability.

Description

technical field [0001] The invention relates to a method for detecting chromium element in jelly, which is mainly used for detecting the content of trace chromium element in jelly and dairy products. Background technique [0002] Chromium is a multivalent metal with hexavalent Cr(Ⅵ) and trivalent Cr(Ⅲ) forms, and the difference in valence states has completely different effects on organisms and the environment. Cr(III) is an essential trace element for the human body. It exists widely in various organs and tissues of the human body and plays a very important role in maintaining human health. It can have a positive effect on insulin, enhance the efficacy of hematopoietic cells, and ensure normal glucose metabolism. If the human body is deficient in chromium, blood sugar will increase, and in severe cases, it will cause diabetes. Although Cr(Ⅲ) is an essential trace element for the human body, hexavalent chromium Cr(Ⅵ) has obvious toxicity to the human body, is irritating an...
