电感耦合等离子体发射光谱法测定丁辛醇废水中钠的不确定度评估
Uncertainty Assessment of Sodium Determination in Butanol-Octanol Wastewater by Inductively Coupled Plasma Emission Spectrometry
摘要
Abstract
Inductively Coupled Plasma(ICP)emission spectrometry was used to determine the sodium(Na)content in butanol-octanol wastewater.The measurement uncertainty was calculated to objectively assess the accuracy of the test results and identify key points for improving method precision and accuracy.The results showed that the Na content in the butanol-octanol wastewater sample was(0.59±0.08)%(k=2),with a correlation coefficient of 0.999 8 for the calibration curve.The relative standard deviation(RSD)of the test results was 0.88%,which matched the sodium content determination results obtained by atomic absorption spectrometry for the same sample.This indicates that the method exhibits good precision and accuracy.关键词
