乙醇燃料中Cr、Ni、Pb 和 V检测方案(微波等离子体光谱仪(MPT、MIP))

通过微波等离子体原子发射光谱仪直接分析乙醇燃料中的 Cr、Ni、Pb 和V 摘要： A simple dilute-and-shoot procedure for determination of Cr， Ni， Pb and V in ethanol fuel byMicrowave Plasma-Atomic Emission Spectrometry (MP-AES) is proposed. Samples were easilyprepared and neither special nor expensive gases were needed for performing analyses. All limits ofdetection from 0.3-40 ug/L were compatible with the requirements taken into account whenconsidering fuel impacts on environment and engine performance.
