Abstract
Objective To establish an atomic fluorescence spectrometric method for the determination of Pb in film coating powder with iron. Methods The sample was digested by the method of pressure digestion tank in the system of nitric acid - hydrogen peroxide, and then extracted by MIBK in 6-7mol/L hydrochloric acid to remove iron, and detected after being disposed. Results The recovery is 99.2% -101.5% and the RSD is 0. 81% ( ft = 6). Conclusion The method can effectively eliminate interference to determinate about iron and has better repeatability and recovery.关键词
