摘    要:Effect of ethanol on corrected intensity,i.e.the intensity corrected for the rate at which an analyte solutionenters ICP,of lines of 10 rare earth elements,Mg,Fe and Cd have been studied,Compared to the aqueous case,the introduction of an ethanol solution results in a decrease in corrected intensity.For all the ionic lines and theatomic lines of Cd,the corrected intensities decrease steadily with increasing ethanol concentration from 0 to95 vol%.while for the atomic lines of the other elements,the corrected intensities have minima at certainethanol concentration.For a given element,the higher the excitation energy of a line,the greater the decrease inthe corrected intensity with the introduction of ethanol,The depression of corrected intensity by ethanol islinearly related to excitation energy.The above results have been used for identifying the ionization states of 38lines of rare earth elements and estimating their excitation energies.
