摘　　要：提出了萃取-分光光度法和火焰原子吸收光谱法测定钢中硼的两种方法,比较了两者的线性范围、检出限、样品测定结果等。试验发现:分光光度法和火焰原子吸收光谱法在硼含量分别为0.11～3.2 mg·L-1和0.05～3.24 mg·L-1范围内时,吸光度与其质量浓度呈线性关系,检出限(3S/N)分别为0.033,0.036 mg·L-1。经检验,两种方法的测定结果之间无显著性差异。In this paper, methods of extraction spectrophotometry and flame AAS for determination of boron in steel were studied and compared. It was found that linearity of working curves was ranged in boron concentration of 0. 11-3.2 mg·L^-1 for spectrophotometry and 0. 05-3. 24 mg·L^-1 for FAAS. Detection limit （3S/N） was 0. 033 mg·L^-1for spectrophotometry and 0. 036 mg·L^-1 for FAAS. No significant difference among the analytical results of the 2 methods was found.
