察尔汗盐湖畔土壤中元素含量特征研究

Characteristics of Soil Element Content around Qarhan Salt Lake

文章采用电感耦合等离子体发射光谱法(ICP-OES)、等离子体质谱法(ICP-MS)和容量法,对察尔汗盐湖湖畔某处100~500 m的13种元素进行了含量测定分析。结果表明,在11~20号元素中Na、Cl和S元素,在距盐湖200 m处质量分数达到最高值,Si、Ca、Al、K和Mg元素,在200m处质量分数达到最低值,P、Se、Rb、Sr和Ba元素受盐湖距离的影响不大。

In this article,the contents of 13 kinds of elements in the range of 100~500m in Qarhan Salt Lake and some important elements in some salt lakes were determined by inductively coupled plasma emission spectrometry(ICP-OES),plasma mass spectrometry(ICP-MS)and volumetric method.The results showed that among elements 11~20,the mass fraction of Na,Cl and S reaches the highest value at 200 meters away from the salt lake,while the mass fraction of Si,Ca,Al,K and Mg reaches the lowest value at 200 meters away,and the elements of P,Se,Rb,Sr and Ba are not affected by the distance from the salt lake.
