Determination of Boron in Low-Alloy Steel by ICP-AES

A method for the determination of boron in low-alloy steel using ICP-AES with calibration of standard additions was studied in this paper.Experimentals including sample dissolution,analytical line selection,interferences of coexisting elements,background correction and working parameters of the spectrometer were studied and optimized.Under the optimum conditions,detection limit of boron was 0.002 mg·L-1,relative standard deviation was less than 2% and recovery was in range of 95%-108.6%.The method was simple to operate,its detection limit,precision and accuracy were satisfactory and fufilled all requirements of the analysis.
