Abstract

The invention discloses a method for rapidly determining 27 elements in a mango leaf by graphite digestion ICP and ICPMS, concretely a research method for determining macro and trace elements in the leaves of Tainung mangos in different producing areas and periods on the basis of ICP-OES and ICP-MS. The method comprises the following steps of (1) early-stage treatment of a sample; (2) calibrationof a sample and a detection limit; (3) sample processing; (4) instrument work parameter setting; and (5) sample determination. The sample is digested by a graphite digestion instrument, and the optimized ICP-OES and ICP-MS method is used to research content of inorganic composition elements in the mango leaf. The measured content of the inorganic elements is calculated and analyzed by a Duucan newmultiple range method in a DPS data processing system, and thus, the 27 elements in the mango leaf are determined and analyzed rapidly.

Description

【Technical field】 [0001] The invention belongs to the technical field of element determination in mango leaves, in particular to a graphite digestion-ICP and ICPMS method for rapidly determining 27 elements in mango leaves. 【Background technique】 [0002] Mango, belonging to Anacardiaceae, is widely planted in tropical and subtropical regions and is one of the most important tropical fruits in the world. Mango fruit is smooth and tender, with unique taste and flavor. Because it is juicy, delicious and nutritious, it is also rich in beneficial mineral elements and health-promoting compounds, such as carotene, ascorbic acid, mangiferin, etc. It also has the effect of preventing cancer. It is known as the king of tropical fruits. China is one of the largest mango producing countries in the world. Its main planting areas are Hainan, Guangxi, Guangdong, Yunnan, Sichuan, Fujian, Guizhou and other places. According to the survey, in 2010 the national mango planting area was 129,0...
