| 摘 要： | 本文报道了采用ICP－AES法测定滑石中的成分。将滑石试样经碳酸钠、硼砂混合熔剂熔融、酸浸取,用电感耦合等离子体原子发射光谱法（ICP－AES）同时测定SiO2,MgO,CaO,Al2O3,Fe2O3,方法回收率在98.8%-104.0%,测定的RSD(n=6)在0.12%-0.24%之间,测试结果与部颁标准的化学分析法基本相符。

| Abstract: | The standard talc sample was fused with Na 2CO 3 and Na 2B 4O 7 and then the fused disc was dissolved with HCl solution.SiO 2,MgO,Al 2O 3,Fe 3O 2 and CaO in talc samples were determined simultaneously by ICP-AES.The optimum analytical line with high sensitivity and low spectral interference were carefully chosen.The sources and properties of the interference were discussed.The recoveries for these elements were 98.8%-104.4%,with precision of 0.12%-2.4% RSD (n=6).The results of major and minor components in talc samples by this method were in agreement with those provided by the standard method. |
