摘要
对微库仑法测定原油盐含量的影响因素进行了研究。结果表明,在测量过程中影响结果准确性的因素主要有电解池的处理、原油的预处理、萃取效率、干扰物质等,并对标准物质的回收率进行考察。针对以上研究结果,指出了在实际分析过程中应注意的问题和提高分析准确度的一些措施。
The factors affecting determination of salt content in crude oil with micro-coulometric method were studied. The results show that treatment of electrolytic bath, pretreatment of crude oil, extraction efficiency and interfere materials are the main factors affecting accuracy of final results. At last,some measures to improve the accuracy of determination were suggested.
