摘要
Abstract
The concentration of the heavy metal elements in surface water is related to the sample collection and preservation under the different conditions.Addition of the fixing agent and sedimentation separation will cause different analysis results.In the study of the Characteristics of heavy metal elements and condition experiment,the results showed that the determination of the dissolved metal ions in surface water must carry out sedimentation separation first,then add the nitric acid after blank checked,in order to ensure the analysis accurate,stable and objective to reflect the water quality of surface water.关键词
