摘　　要：文章利用电感耦合等离子体原子发射光谱法(ICP-AES),采用多谱线拟合分析技术测定低合金钢中的硼,经仪器条件试验对元素分析谱线、共存元素干扰及校正、检出限等进行研究,确定测定范围为0.001%~0.100%。该方法采用盐酸硝酸混合酸分解试样后,利用仪器直接进行测定,建立了一种简单和快速测定低合金钢中硼含量的分析方法,具有良好的精密度和准确度。In this paper,the boron in low-alloy steel is determined with ICP-AES and multispectral fitting analysis technology.The analytical spectral lines of elements,interference and correction of coexistence elements as well as detection limits are studied by the condition experiments with instrument.The measuring range is determined to be 0.001%~0.100%.With the method,samples are dissolved with the mixed acid of hydrochloric acid and nitric acid,then they are directly determined with instrument.As a result,a simple and rapid analysis method for determining boron content in low-alloy steel is established,which is with good accuracy and precision.
