【摘要】 文章采集了莲花山尾矿库的尾矿样本以及周边环境样本,微波消解样本后,用电感耦合等离子体质谱仪(ICP-MS)分析测定了样本中12种重金属的含量。结果表明莲花山脚废弃尾矿和污染土壤都含有大量的Al、Mn、Fe、Cu和As元素,并含有一定量的Cr、Ni、Cd和Pb等重金属。渗滤液、小溪及蓄水池中除了Cr、Cd和Pb的含量很低外,其余9种元素均有一定浓度。尾矿的酸性物质使重金属不断溶出,通过渗滤液进入水体,然后污染土壤,严重影响了周边环境。更多还原

【Abstract】 In the paper, the tailing, soil and water samples were collected around Lianhuashan tungsten mine area, and than digested by CEM-MARS XPRESS microwave clear up system. Twelve elements were determined by ICP-MS. The results showed that the tailing and, soil contains a large number of metal elements, include Al, Mn, Fe, Cu and As. And contains a certain amount of Cr, Ni, Cd and Pb and other heavy metals. Waters around Lianhuashan tungsten mine area contain a certain concentration of metal elements, but the Cr, Cd and Pb content were very low. The dissolution of heavy metal in the water was enhanced by the acid material of tailings. The soil was polluted, which seriously affect the surrounding environment.更多还原
