微波消解ICP-AES法测定白术中常量及微量元素

DETERMINATION OF CONSTANT AND TRACES ELEMENTS IN THE ATRACTYLODES MACROCEPHALA KOIDZ BY MICROWAVE DIGESTION ICP-AES METHODS

采用微波消解ICP-AES法测定了白术中的Ca、Mg、Fe、Mn、Zn、Sr、Cu等常量及微量元素的含量,相对标准偏差为0．94％-9．33％,回收率为91%-103％。该方法适用于植物中多种元素的测定,结果令人满意。

Microwave digestion ICP-AES method was used for the determination of Ca, Mg, Fe, Mn, Zn, Sr and Cu in koidz. The relative standard deviation of this method was 0. 98%-9. 33% and the recovery was 91%- 103%. This method is proved to be simple, rapid and reliable. It is very useful for researching the nutritional and pharmaceutical value of koidz.
