Abstract: Sample of multi-componental deoxidizer was fused with a mixture of Na2CO3 and H3BO3,and the melt was dissolved in HCl. An aliquot of the sample solution was taken and used for ICP-AES determination of contents of Ca,Ba,Al and P. Analytical conditions,including choice of fusing agents,pH value and concentration of sample solution,were studied experimentally. Wavelengths of 315.887,233.527,213.618 and 309.271 nm were selected as analytical spectral lines for the determination of Ca,Ba,Al and P respectively. The proposed method was used in the analysis of standard sample (GSBH 13603-96 and YSB14605-2001),giving values of recovery in the range of 95.0%-103.5% and values of RSD′s (n=11) less than 3.0%. The results obtained conformed with the standard values.
