摘要:建立了测定林地土壤中9种金属元素(Ba、Cu、Co、Cr、Mn、Ni、Pb、V、Zn)的快速消解-电感耦合等离子体发射光谱法。采用聚丙烯管作为消解容器,优化了酸使用量和消解时间,在0.1 g称样量的情况下,加入4 mL王水和0.3 mL HF,消解温度为125℃,消解时间为90 min,赶酸时间为20 min,消解液采用电感耦合等离子体发射光谱仪测定。采用优化后方法对8种不同类型标准土壤样品进行测试,其测定值与与标准值一致。同时采用该方法与环保部标准前处理方法进行实际林地土壤样品的比较验证发现:两种方法无显著性差异(P>0.05)。相比于现行标准方法,此消解方法用酸量少,操作简单,设备投入小,实验效率高,适合批量土壤样品中的金属元素分析。
A sample preparation method was developed for quantitative detection of Ba,Cu,Co,Cr,Mn,Ni,Pb,V and Zn in soil by inductively coupled plasma optical emission spectrometry(ICP OES).The results obtained from this method were in good agreement with the eight different types of certification reference soil,thus demonstrating the excellent accuracy of the selected method.The real forest soil samples were determined by both optimized method and standard method,and the results showed that there were no significant difference(P>0.05)between the two methods.The developed method has the merit of less reagent usage,simple operation,inexpensive instrument and high efficiency and is fit for batch determination.
