摘　　要：利用同步辐射 X射线荧光分析方法研究了生长在金属矿山上的植物体内重元素的组成与含量 ,以及植物对重元素的富集特性。对采自安徽琅琊山铜矿的梓木草 (Lithospermum Erythrorhizon)和山慈菇(Tulipa Edulis) 2种植物的重元素分析结果表明 ,在锌木草各营养器官之间 ,各种重元素的分布极不均匀 ,Mn、Fe、Cu、Zn等主要富集在多年生根中。山慈菇叶片中的重元素的含量 ,比其他地方的同种植物较高。与一般植物体内重元素检测方法相比 (如火焰原子吸收光谱法 ) ,该法的灵敏度高 ,样品处理简便。The composition,contents and enriching properties of heavy elements in the plants growing in mental mines were studied by X ray fluorescence of synchrotron radiation(SR XRF). Lithospermum Erythrorhizon and Tulipa edulis were plucked in the copper mine in Langya mountain of Chuzhou city in Anhui province.The heavy elements in the nutrition organs of the two plants are distributed unevenly.For example,Mn,Fe,Cu and Zn are abundant in the perennial roots of Lithospermum Erythrorhizon ,and the contents of heavy elements in the blades of Tulipa Edulis are higher than those of the identical plant anywhere else.Compared with general method(such as FAAS) to measure heavy elements in the plant,SR XRF is more sensitive and more convenient for treatment of the sample.
