| 摘要: |
| 采集锑接触作业人员尿样,以铜作为基体改进剂,用原子吸收分光光度计(石墨炉)测定尿的锑含量。结果建立了尿中锑的石墨炉原子吸收测定法。该方法线性范围为0~100μg/L,最低检出浓度为1.75ng/ml,回收率为101.0%~102.8%,相对标准偏差2.2%。该方法的线性好,精密度和准确度好,对于锑接触者的尿中锑含量测定明显高于非接触者。 |

| Abstract: |
| Build up the graphite furnace atom absorbent method to measure Sb in urine.Collect the urine sample,use copper as the matrix improvement,use the atomic absorption light photometer(the graphite furnace) to measure.The method's linearity scope is 0~100 μg/L,the lowest checked density is 1.75 ng/ml,the recovery rate is 101.0%~102.8%,the opposite standard deviation is 2.2%.The linearity of the method is well,the precision and accurate degree is good,the measurement of the Sb consistency in the urine of the Sb contact is obviously higher than the consistency in the intact. |
