摘　　要：采用微波消解——电感耦合等离子发射光谱法(ICP-AES)对攀枝花某钒钛矿区十种优势植物地上部分和地下部分中Pb,Zn,Cu,Cr,Cd,Ti等无机元素含量进行了测定。结果表明,该方法相对标准偏差均在5.0%以下,通过加标回收实验,回收率在92.90%-103.85%之间,与传统的方法相比,本法具有较好的准确度和精密度,且灵敏度较高,能同时测量多种元素等优点。Ten kinds of dominant plants in Vanadium/Titanium mine area were collected,the contents of heavy metals including Pb,Zn,Cu,Cr,Cd and Ti of which aboveground and underground parts were determined by ICP-AES using microwave digestion,respectively.All samples of the plants were digested with HNO3-H2O2 system.The relative standard deviation was less than 5% for all the elements,and the recoveries were 92.90%~103.85% by adding standard recovery experiment.This method was simple,sensitive and precise and can perform simultaneous multi-elements determination compared with conventional method of the plants determination,which could satisfy the sample examination request and provide scientific rationale for determining inorganic elements of plants.
