摘要
研究了轻质油中痕量砷的几种样品处理方法。实验表明,石墨炉原子吸收光谱法测定时,用碘-甲苯和H2O2-HNO3相结合处理轻质油样品较为合适,萃取效率可达90％。并对影响萃取测定的其它因素作了初步探讨。
The determination of traces of arsenic in light oil by GFAAS was described. The analytical results show it was suitable with the methods of combine I2 - Toluene and H2O2- HNO3 to treat oil sample. The efficiency of extraction is 90 % 。
