Abstract
The simultaneous determination of inorganic mercury and antimony was evaluated by the application in lead-base alloys through solid-phase extraction (SPE) coupled with hydride generation-double channel atomic fluorescence spectrometry (HG-DC-AFS) using a separation/preconcentration step on an Amberlite XAD-16 resin packed column. The high selective SPE was based on the similar properties between non-polar resins and molecular covalent compounds e.g., HgBr2 and SbBr3 formed in concentrated H2SO4 and HBr media. Various experimental conditions affecting the solid-phase extraction and determination of the analytes had been investigated. Under the optimized conditions, the limits of detection of 0.17 μg L-1 for Hg(II) and 1.66 μg L-1 for Sb(III) were obtained. The precisions (RSD) for seven replicate measurements of 20 μg L-1 Hg(II) and Sb(III) were 0.37 and 2.9 %, respectively. The developed method was validated by spike test and was applied to the separation/preconcentration of Hg and Sb from two lead-base alloys matrices.
