摘　　要：从定性和定量两个方面联合分析了皮蛋蛋壳表面斑点的化学成分,XPS技术检测出黑色斑点由C、O、N、Na、Ca、Fe、Cu、S、Zn、P等元素组成,未检出Pb元素,Cu以Cu+存在;XRD技术得出黑色斑点的次相物质是Cu2S;ICP-AES测定结果表明,斑点颜色越深,铜的含量越高。The chemical composition of surface spots on the preserved egg shell was studied quantitatively and qualitatively.The XPS technique found many constituent elements including C, O, N, Na, Ca, Fe, Cu, S, Zn, P, etc. The Pb element was not found. Cu in Cu＋existed in the black spot. The second phase material was Cu2S in the black spot. The ICP-AES technique was used to determine several conventional elements of five kinds different color of eggshell. The result showed that content of the copper was high when the color of the spots was deep.
