| 摘 要： | 采用石墨炉原子吸收法对空气中铬酸雾进行测定,方法在待测液中铬质量浓度为1~10μg/L范围内线性良好,r=0.999 6,检出限为0.001 mg/m~3,测定结果的相对标准差为1.64%~4.53%,样品加标回收率为91.0%~95.4%,且用该方法与《固定污染源排气中铬酸雾的测定二苯基碳酰二肼分光光度法》(HJ/T 29—1999)分别测定实际样品中铬的质量浓度,结果无明显差异。

| Abstract: | Chromic acid mist in the air was measured by graphite furnace atomic absorption spectrometry.The method had a good linearity in the mass concentration range of 1 to 10μg/L, r=0.999 6.The detection limit was 0.001 mg/m3 .The relative standard deviation of the measurement was 1.64%~4.53%, and the recovery rates were 91.0%~95.4%.There was no apparent differ-ence in the determination of chromium mass concentration between this method and the《HJ/T 29-1999》 method. |
