A simple and rapid method for the simultaneous separation and determination of the inorganic ionic forms of As(III), As(V), Sb(III), Sb(V), Tl(I), and Tl(III) in river water samples is described.

Zinc oxide levels in cosmetic formulations are commonly analyzed by atomic absorption (AA) spectroscopy using the fusion method for sample digestion, a labor-intensive and time-consuming process that causes lengthy delays in product manufacturing.
