摘要
对按汽油中锰含量的测定方法 SH/T0711-2002《原子吸收光谱法测定汽油中锰含量》测定的结果影响因素一一分析,对分析准确度进行考察。实验结果表明,曲线绘制、标样选择、回收率等因素都能影响分析结果的准确度,对日常检测锰含量在0.25-26 mg/L范围内的汽油需要注意的方面,解决了汽油中锰含量测定不准的难题。
According to the gasoline manganese content of the measurement method of the SH/T 0711-2002 ＂atomic absorption spectrometry manganese content in gasoline,the result of one impact factors were analyzed,the accuracy of analysis for an investigation.The experimental results show that the curve plotting,selection,recovery results factors can affect the accuracy of the results of the analysis on the daily inspection manganese content in 0.25-26 mg/L within the scope of the gasoline needs to pay attention,solve the content determination of manganese in gasoline to difficult problems.
