摘要
本文研究浙江省杨梅果实中^(87)Sr/^(86)Sr同位素比值与产地的相关性;利用热电离同位素质谱对浙江宁波和台州杨梅产区的^(87)Sr/^(86)Sr同位素比值进行测定,优化了锶元素的纯化程序,对^(87)Sr/^(86)Sr同位素比值进行统计分析,结果表明:浙江省宁波市杨梅果实的^(87)Sr/^(86)Sr同位素比值高于台州仙居杨梅果实^(87)Sr/^(86)Sr同位素比值,浙江省宁波和台州杨梅主产区杨梅果实的^(87)Sr/^(86)Sr同位素比值具有显著性差异;可以通过^(87)Sr/^(86)Sr同位素比值对浙江省杨梅果实进行原产地溯源。
The correlation between ^(87)Sr/^(86)Sr isotopic ratio of bayberry fruit in Zhejiang Province and its producing area was studied in this paper.Isotope ratios of ^(87)Sr/^(86)Sr in Myrica rubra of Zhejiang Province producing areas were determined by thermal-ionization mass spectrometry.The purification procedure of strontium was optimized.The ^(87)Sr/^(86)Sr isotopic ratios in Myrica rubra from different producing areas were statistically analyzed.The results showed that the isotopes ratio of ^(87)Sr/^(86)Sr in bayberry from Ningbo were the higher than Taizhou.There are significant differences in ^(87)Sr/^(86)Sr isotopic ratios of Myrica rubra fruit from Ningbo and Taizhou in Zhejiang Province.The ^(87)Sr/^(86)Sr isotope ratio in Myrica rubra from Zhejiang Province can be used to trace the origin.
