摘要
利用TN-100总氮仪分析芳烃中微量的氮含量,确定影响氮含量分析准确性的主要因素。用标准曲线校准,平均回收率为99.07%,相对标准偏差小于5%。该方法简便、准确,可用于芳烃中微量氮含量的测定。
The TN-100 total nitrogen instrument is used to analyze the nitrogen content in aromatics,and the main factors influencing the accuracy of the nitrogen content analysis is determined. When using standard curve to make calibration,the average recovery rate is 99.07%,the relative standard deviation is less than 5%. This method is simple,convenient and accurate,and can be sed for determination of nitrogen content in aromatics.
