| 摘 要： | 建立了电感耦合等离子质谱法(ICP-MS)测定电吸附找矿泡塑样品中钒、铬、锰、钴、镍、铜、锌、镓、铌、钼、银、镉、金、铊、铅和铋等16种微量元素的方法。进行了灰化法-王水提取、硝酸-过氧化氢消解-王水提取和沸水浴王水提取试样的比较实验，以硝酸-过氧化氢-王水提取法为最佳样品分解方法。对仪器工作参数进行了优化, 选取103Rh和185Re作为测定元素的内标元素, 进行了测定同位素的选择及干扰的消除等实验, 测定元素校准曲线的相关系数都在0.999 8以上, 各元素的检出限分别为0.001～2.2 μg·g-1, 精密度介于1.39%～4.84%之间, 样品加标回收率为94.86%～105.2%。方法简便快速，已应用于大量泡塑样品分析。 |

| Abstract: | An ICP-MS method was established for the determination of sixteen trace elements,V,Cr,Mn,Co,Ni,Cu,Zn,Ga,Nb,Mo,Ag,Cd, Au,Tl,Pb and Bi in electrical absorption prospecting polyform.Three methods for polyform samples(ashing method,extraction by HNO3+H2O2 and digestion with aqua regia) were compared and the results showed that the second method is the best one.The best operational paramenters of X series ICP-MS were confirmed,the inner standard 103Rh and 185Re were selected for the determination of elements,and... |
