摘要
通过实验,研究了电感耦合等离子体原子发射光谱(ICP-AES)法测定铬钼合金钢中磷、硅、锰、铬、镍、钼、铜、砷、锑和锡10种元素质量分数的方法。阐述了ICP-AES分析法测定实验的试剂制备、方法、测量条件和分析线选择,得到了各元素测定标准曲线。实验结果表明,该方法测定元素线性相关系数大于等于0.9994,相对标准偏差RSD在0.19%~2.61%,满足测定铬钼合金钢中磷、硅、锰、铬、镍、钼、铜、砷、锑和锡10种元素质量分数的需求,操作简便快捷,在快速检测中具有较好的实用性。
Based on experiments inductively coupled plasma atomic emission spectrometry(ICP-AES)method to determine the mass fraction of 10 elements of phosphorus,silicon,manganese,chromium,nickel,molybdenum,copper,arsenic,antimony and tin in chromium-molybdenum alloy steel has been studied.The preparation of reagents,methods,measurement conditions,and analysis line selection of the ICP-AES analysis method were described,the standard curve for the determination of each element was obtained.The experimental results show that the linear correlation coefficient is no less than 0.9994,the relative standard deviation RSD is 0.19%~2.61%.The accuracy and precision of the method can meet the requirements of the determination of phosphorus,silicon,manganese,chromium,nickel,molybdenum,copper,arsenic,tin,and antimony in chromium-molybdenum alloy steel.
