| 摘 要： | 基于大量实测数据统计,比较了测定水中铁、锰、汞3种重金属时,样品是否过滤、加酸保存等前处理方式对测定结果的影响,提出铁、锰水样需过滤检测,汞水样不能过滤检测,且3种金属的水样均需加酸保存,这样测定的结果才能根据现行水环境质量标准进行评价。

| Abstract: | Incidents of heavy metals pollution in water have been happened recentaly. Pertreatment of water sample is essential to make a accurate test. Based on a large number of environmental monitoring data of drinking water source area in Jiangsu, the effects of sample''s different pretreatment procedure (filtration, acid preservation) on the test results were compared for Fe, Mn and Hg in water. It was suggested that in order to evaluate the test results by existing environment quality standards, the water sample of Fe and Mn should be filtrated before determination, but the Hg sample should not be filtrated. As to the sample preservation, all the samples for analyzing the three kinds of metals should be acidified. |
