Acid Enhancement of Zinc and Lead Atomic Absorption Signals

Volume 28, Number 6 (Dec. 1974) Page 585-587

Brachaczek, Wanda W.; Butler, James W.; Pierson, William R.


We have been measuring atmospheric particulate Pb and Zn concentrations by atomic absorption. Samples are collected on membrane filters and dissolved in HNO3-HClO4 prior to comparison with aqueous standards, using an Instrumentation Laboratories model 153 dual beam dual channel atomic absorption spectrophotometer equipped with background correction, operating with a stoichiometric air-acetylene flame. The absorption lines are 217.0 nm for Pb and 213.9 nm for Zn.
