| Abstract: | By the dust tilter membrane is dispelled with a lot of HNO3-HF-HClO4 conditions of determinating Pb and Mn with GF-AAS are selected optionally. By using this method, Pb and Mn in dust were daterminated. Results show that the recovery of Pb and Mn are 87%-98% and 94%-105%. Their deviation arc 4.1% and 3.7%, respectively. |
