摘要
文章采用电感耦合等离子体发射光谱仪(ICP-AES)对钒碳合金中钒、锰、磷、硅元素进行联合测定,利用基体匹配法绘制校准曲线,消除基体效应的影响,同时对仪器参数进行了优化。精密度实验结果表明,钒、锰、磷、硅元素的相对标准偏差(RSD,n=11)在0.5%~3.0%之间。通过加入不同浓度的标准溶液进行回收率实验,回收率在95%~110%之间。准确度实验结果表明,各测定元素的实验结果与标准值一致,满足检测方法要求,实现了钒碳合金中钒、锰、磷、硅元素含量的快速、准确测定。
In the paper,the simultaneous determination for elements of vanadium,manganese,phosphorus and silicon in vanadium-carbon alloy is carried out with inductively coupled plasma-atomic emission spectrometry(ICP-AES),calibration curve is drawn with matrix matching method to eliminate the effects of matrix effects as well as instrument parameters are optimized.The precision experiment results showed that relative standard deviation(RSD,n=11)for elements of vanadium,manganese,phosphorous and silicon was 0.5%~3.0%.The recovery rate experiment results showed that recovery rate was 95%~110%through adding standard solutions of different concentrations.The accuracy experiment results showed that the experimental results of each determination element were consistent with standard values,which could meet the requirements of detection method so that rapid and accurate determination for elements of vanadium,manganese phosphorus and silicon in vanadium-carbon alloy is realized.
