| 摘 要： | 采用H2SO4-H2O2萃取轻质油样品,以盐酸为载液,硼氢化钾为还原剂,通过氢化物发生-原子荧光法测定轻质油中的砷含量。结果表明,用该方法测定轻质油中砷含量的检出限为0.12μg/L,相对标准偏差小于3%,加标回收率为98.6%~101.3%。该方法灵敏度高,测定结果准确可靠,可广泛应用于轻质油样品中砷含量的测定。

| Abstract: | Using hydrochloric acid as carrier, KBH4 solution as reducing agent,the arsenic content in the light oil sample extracted with HzSO4 -H202 was determined by hydride generation - atomic fluorescence spectrometry. The results showed that detection limit of arsenic content was 0.12 μg/L, the relative standard deviation （RSD） was less than 3%, and the recovery rate of adding standard material was 98. 6% - 101.3%. This method is sensitive,rapid,and accurate. It can be widely used for the determination of arsenic content in light oil. |
