摘要:
采用实验室与现场相结合的方法对砷快速测定方法的可靠性和应用价值进行研究。研究显示,该法检出限为2μg/L,具有较好的准确度,对于砷质量浓度>5 μg/L的水样,相对误差为1.00%~10.00%,对于砷质量浓度为5μg/L的水样,虽然相对误差较大,为22.40%,但其测定结果在砷污染快速监测可接受的结果范围内;精密度较高,相对标准差为5.27%~16.54%;同时具有较好的再现性。该方法能减少砷污染筛查的工作量,可满足应对砷污染突发事件应急监测的需求。

Abstract:
The study was conducted to evaluate the reliability and practical value of rapid arsenic detection method using both laboratory and locale experiments. The study showed that the method detection limit was 2 μg/L. The method had good accuracy, the RE was in the range of 1.00%~10.00% when the concentration of arsenic was over 5 μg/L in water. Though the RE was a little high which was 22.40%, when the concentration of arsenic was 5 μg/L, it was acceptable for the rapid detection of arsenic pollution. The method had a good precision and the RSD was in the range of 5.27%~16.54%, and also had a good reproducibility. The method could reduce the workload of pollution screening on arsenic and meet the needs of ansenic pollution incidents.
