The particulate6 are collected on Whatman 41 cellulose filters and decomposed with sulfuric acid and hydrogen peroxide; bismuth is then measured by hydride generation/atomic absorption spectrometry. The detection limit is 0.08 ng m" if 500 m' of air is filtered through an 11-cm filter. Generally, th

โฆ Synopsis
l,lO-Phenanthroline is used to mask the matrix interference from nickel ions in the determination of bismuth and antimony by hydride generation/atomic absorption spectrometry. The suppression of the absorption signals is eliminated up to a 10 OOO-fold of Ni".
