Efficiency of chemical generation of volatile species of zinc from non-acidic conditions

Chemical vapour generation assisted by Cr3+/KCN coupled to atomic fluorescence spectrometry for ultrasensitive determination of cadmium in water and rice samples

“…18 transition metals so far, 14 and among them, especially Ag, Au, Cu, Pd and Zn yielded relatively high CVG efficiencies (>10%). 14,52–56 However, modified CVG configurations that allowed for rapid mixing with a reductant (without a reaction coil) were required along with the use of reaction modifiers that were entirely distinct from those used in this study. 14 In this work, supporting evidence was provided for Zn when no detectable signal was obtained even with 50 μg L −1 Zn 2+ if the CVG setup was coupled to ICP-MS and operated under optimal conditions found for Cd (Table 1).…”
