摘　　要：样品经HCl消解后,分别选择Mn 279.5 nm,Cu 324.8 nm,Zn 213.9 nm,K 766.5nm谱线作为分析线,采用火焰原子吸收光谱法测定低碳钢中锰、铜、锌、钾。4种元素的质量浓度在一定范围内与吸光度呈良好的线性关系。方法检出限分别为0.009 5,0.013 8,0.002 9和0.003 3 mg/L。对低碳钢样品进行测定,相对标准偏差（n=7）均在1%以下,加标回收率在95%~104%之间。The sample was digested with HCl.Mn 279.5 nm,Cu 324.8 nm,Zn 213.9 nm and K 766.5 nm were used as analytical lines.The content of manganese,copper,zinc and potassium in low-carbon steel was determined by flame atomic absorption spectrometry.The mass concentration of four elements showed good linearity with absorbance in certain range.The detection limits were 0.009 5,0.013 8,0.002 9 and 0.003 3 mg/L,respectively.The low-carbon steel sample was determined by the proposed method.The relative standard deviations（RSD,n=7） were less than 1 %.The recoveries of standard addition were 95 %-104 %.
