Abstract

Interferences in the atomic-absorption spectroscopy of cultures and plant materials for Ca and Mg are eliminated by addition of Sr and HClO₄. The method described yields good accuracy and precision, and is suitable for routine analysis of large numbers of samples containing widely varying concentrations of unknown and interfering ions.
