火焰原子吸收光谱法测定牡丹花中6种金属元素

FAAS Determination of 6 Metal Elements in Peony Grown in He'ze

用火焰原子吸收光谱法测定了在菏泽种植的牡丹花中的6种金属元素（铜、锌、铁、锰、镍、钴），牡丹花样品经烘干、灰化及灼烧，用硝酸（2＋98）浸取并溶解残渣。用6种元素的标准溶液制作了各自的标准曲线，所得线性回归方程的相关系数在0．9937至0．9990之间。在紫牡丹样品的基础上加入一定量6种元素的标准溶液作回收试验，得到回收率在99．0％～105．3%之间，基于所得分析结果，对本地产牡丹的开发利用作了简要探讨。

Six metal elements, i e. , Cu, Zn, Fe, Mn, Ni and Co, in peony grown in He＇ze were determined by FAAS. Peony sample was ashed, ignited and the residue was taken up with HNO3 （2＋98）. Standard curves of the 6 elements were prepared by using the respective standard solutions, and linear relationships with correlation coefficients in the range from 0. 993 7 to 0. 999 0, were obtained. Recoveries, obtained by standard addition method, were in the range of 99.0%- 105. 3%. On the base of the analytical results, a brief discussion on the exploitation of peony was given.
