摘要:

目的:测定美洲大蠊卵鞘中16种元素的含量情况。方法:样品采用高氯酸和硝酸(1:4)湿法消解,原子吸收分光光度法
测定美洲大蠊卵鞘中Co、Mg、Zn、Ni、Se、Cr、Cu、Mn、Fe、Ca、Na、K 12种元素,原子荧光光度法测定Hg、Pb、As、Cd的含量。结
果:发现美洲大蠊卵鞘中除了含有人体必需的多种微量元素外,还富含Ca、Mg、Zn、Mn、Fe等元素,基本不含重金属Cr、Hg、Pb、
As和Cd。结论:为进一步研究和综合利用美洲大蠊卵鞘提供依据。

Abstract:

Objective: To determine 16 kinds of element in periplaneta Americana ootheca. Methods: Perchloric acid and nitric acid
(1:4)wet digestion was applied in samples and 12 kinds of element: Co, Mg, Zn, Ni, Se, Cr, Cu, Mn, Fe, Ca, Na, K and the content of
Hg, Pb, As, Cd were determined by atomic absorption spectrophotometry and atomic fluorescence spectrophotometry respectively in
periplaneta Americana ootheca. Results: Periplaneta Americana ootheca contains plenty of essential trace elements to human, and it is
also rich in Ca, Mg, Zn, Mn, Fe and other elements. But there is no any heavy metal like Cr, Hg, Pb, As and Cd. Conclusion: To
provide basis for the further study and comprehensive utilization of periplaneta Americana ootheca.

Key words: periplaneta Americana, ootheca, element analysis, atomic absorption spectrophotometer, atomic fluorescence photometer
