广西龙江河泥中镉及某些金属元素含量分析

Analysis of Cadmium and Some Metal Elements Content of Longjiang River Silt in Guangxi

采用火焰原子吸收分光光度法对广西龙江河泥中镉和某些金属元素的含量进行了测定,分析结果显示,Ca、Cu、Fe、K、Mg、Mn、Na、Zn等元素的含量在正常范围之内,Cr、Pb、Hg、Sn、Sb等元素的含量低于国家标准,而金城江市以下的龙江河泥中Cd元素含量仍超过我国土壤自然Cd含量的最大值。

The contents of Cadmium and other elements in Longjiang river silt of Guangxi were determined by flame atomic absorption spectrometry .Analysis results show that contents as Ca ,Cd , Cu ,Fe ,K ,Mg ,Mn ,Na ,Zn are in the normal range .The contents of Cr ,Pb ,Hg ,Sn and Sb are lower than the national standard values .In the lower part of Jinchengjiang ,the Cd content of Longjiang river silt is more than the maximum value of natural soil Cd content in China .
