摘　　要：利用同步辐射(SR)X射线荧光(XRF)分析方法,对淮河中游10个产地的沉水植物金鱼藻 (Ceratophyllum demersum) 叶片进行了元素分析,检测出的20多种主要重元素中,重金属元素有Mn, Fe, Co, Ni, Cu, Zn, Rb, Sr和Zr等,并显示了金鱼藻对Mn,Fe和Zn有较强的吸收能力和抗富营养污染本领。分析结果表明,颍上县的颖河、洪泽湖和滁州的铜矿山水库中的金鱼藻所富集的重金属较多。The leaves of submerged plant Ceratophyllum demersum, gathered from 10 different regions in the middle part of the Huai River, were analyzed by SR XRF. We found that there are more than 20 heavy metal elements in the XRF spectra. They are mainly Mn, Fe, Co, Ni, Cu, Zn, Rb, Sr and Zr. C. demersum has shown good capability of concentrating heavy metal elements Mn, Fe and Zn, and excellent ability of protecting super-nutrition contamination. It was also shown that C. demersum from the Ying River of Yingshang county,the Hongze Lake and the reservoir of copper mine in Chuzhou city of Anhui Province, respectively, enriched more heavy elements than that from other places.
