摘要
通过改进实验方法,利用极性溶剂抽提原油中的无机盐,通过滴加H2O2溶液去除硫的干扰,然后对抽提液采用微库仑法测定其中的盐含量,从而较好地解决了高硫原油中盐含量测定时硫的干扰问题。结果表明,本方法测量准确度高,精密度较好,操作简便快速,方法加标回收率100±5%,相对标准偏差为3.56%。
A method was developed for the determination of salt content in sour crude oil. Through - periments, we have built a simple and fast method to remove the sulfur interference for salt content determination by adding appropriate amount of H2O2 solution, and selected the best parameters. The experiment results showed that the method have a very good accuracy and precision,the method recovery is 100 ± 5%, and the relative standard deviation (RSD) is 3.56%.
