title: [Determination of major and minor components in standard talc samples by ICP-AES].
abstract: The standard talc sample was fused with Na2CO3 and Na2B4O7 and then the fused disc was dissolved with HCl solution. SiO2, MgO, Al2O3, Fe3O2 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.
