Rare earth/food inspection parameter detection

Rare earth is a collective term for seventeen metallic elements in the periodic table, including lanthanide elements and scandium and yttrium. There are 250 types of rare earth minerals in nature. The earliest discovery of rare earths was by Finnish chemist John Gadolin. In 1794, he separated the first rare earth "element" (yttrium earth, or Y2O3) from a heavy ore resembling asphalt. Due to the scarcity of rare earth minerals discovered in the 18th century, only a small amount of insoluble oxides could be obtained through chemical methods. This oxide was traditionally referred to as "soil" in history, hence the name rare earth. According to the atomic electronic layer structure and physicochemical properties of rare earth elements, as well as their coexistence in minerals and the characteristics of different ion radii that can produce different properties, seventeen types of rare earth elements are usually divided into two groups: light rare earth elements include: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, and europium. Heavy rare earth elements include gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, and yttrium. Classification by extraction and separation: light rare earth (P204 weak acidity extraction) - lanthanum, cerium, praseodymium, neodymium; Middle rare earth (P204 low acidity extraction) - samarium, europium, gadolinium, terbium, and dysprosium; Heavy rare earth (acidity extraction in P204) - holmium, erbium, thulium, ytterbium, lutetium, and yttrium
