| Abstract: | Trace Pb in atmospheric flying-dust was collected by CA-CN microporous filter sheet and then determined by atomic absorption spectrophotometry. This sampling technique was not only simple and time saving but also interfered a little by matrix. Moreover, sampling efficiency could also be satisfied the requirement for analyzing environmental samples. |
