单波长色散X射线荧光光谱法测定原油中盐含量

Determination of salt content in crude oil by single wavelength dispersive X-ray fluorescence spectrometry

提出了一种单波长色散X射线荧光光谱法快速测定原油中盐含量的方法。利用该方法对原油样品中的无机氯含量进行分析,并与传统方法进行了对比。实验结果表明该方法具有高度的灵敏度和准确性,该方法加标回收率在99.04%~99.67%,平行进样的相对标准偏差(RSD)在0.04%~2.09%,能够有效地测定原油中的盐含量。本方法操作简单,准确性高,可作为传统原油中盐含量方法的替代方法。

This method is employed to analyze the inorganic chlorine content in crude oil samples and compared with traditional methods.The experimental results demonstrate that this method has high sensitivity and accuracy,with spiked recovery rates ranging from 99.04%to 99.67%and the relative standard deviations in parallel sample injection ranging from 0.04%to 2.09%,which can effectively determine the salt content in crude oil.This method is simple to operate,highly accurate,and can be used as an alternative to the traditional methods for measuring salt content in crude oil.
