| Abstract: | The article introduces the basic principle and process of anodic stripping voltammetry.The mercury film electrode is used to detect lead and cadmium in nonferrous metal mining area rain runoff.Then the result is trans mitted and preserved.Under the best selected experimental conditions,the relative standard deviation of lead and cadmium is 0.200% and 0.287% while the recovery rate is both between 89.5% and 105%.The determination results are satisfactory. |
