摘要
探讨了用原子吸收空气-乙炔火焰连续测定轻质油中痕量铜的方法,并考察了轻质油中铜的萃取富集方法。实验结果表明,采用I2-甲苯溶液为氧化剂和稀硝酸为萃取剂处理轻质油,并利用原子吸收分光光度法测定油中铜含量,该测定方法简便、快速、准确度高且重现性良好。
The method of determination of copper in light oil by air-acetylene flame atomic absorption was discussed in this paper, and the extraction and enrichment of copper in light oil was reviewed. The experimental results showed that the determination method with light oil dealt by iodine-toluene as oxidant and tenuous nitric acid as extractant, copper determined in light oil by atomic absorption spectrometry was simple, quick, high accuracy and good repeatability.
