岷江水系河水与沉积物中稀土、稀有元素背景值及其特征初探

A PRIMARY STUDY ON THE BACKGROUND VALUES AND FEATURES OF RARE EARTH AND RARE ELEMENTS IN RIVER WATER AND SEDIMENTS FROM THE MINGJIANG RIVER

报告了岷江水系河水及沉积物中８种稀土元素（Ｌａ，Ｃｅ，Ｎｄ、Ｓｍ、Ｅｕ、Ｔｂ、Ｙｂ、Ｌｕ）及８种稀有元素（Ｒｂ、Ｃｓ、Ｓｒ、Ｂａ、Ｓｂ，Ｔｈ、Ｓｃ、Ｕ）的背景值及其特征，并对元素的排列顺序及元素间的相关关系进行了初步探索，还列出了１６种元素在原水及沉积物中的相关矩阵及相互间的相关回归方程。

This paper reports the background values and features of 8 Rare earth elements(La,Cs,Nd,Sm,Eu,Tb,Yb,Lu)and 8 Rare elements(Rb,Cs,Sr,Ba,Sb,Th,Sc,U)in river water and seditnents taken form the Ming-Jiang River.The rank of these elements and the correlation in various elements were studied,and the relation regression equation and relation Matrix of 16 elements in river water(unfilter water)and sediments in this area were also studied.
