TL;DR: A temperature-controlled selective filtration technology for synchronous removal of arsenic and recovery of antimony from the fume produced from reduction smelting process of lead anode slimes was proposed and results showed that porous FeAl alloyed with 20wt.% Cr had a long term stability in a high-temperature sulfide-bearing environment.

TL;DR: In this article, a procedure for the separation and determination of inorganic species of antimony based on the use of coupled high-performance liquid chromatography (HPLC) hydride generation (HG) atomic fluorescence spectrometry (AFS) is described.
Abstract: A procedure for the separation and determination of inorganic species of antimony based on the use of coupled high-performance liquid chromatography (HPLC) hydride generation (HG) atomic fluorescence spectrometry (AFS) is described. Sb(III) and Sb(V) were separated on a miniaturized anion-exchange column (Supelcosil LC-SAX 1, 2 cm × 4.6 mm id) using a 0.06 mol l−1 ammonium tartrate aqueous solution at pH 6.9 as eluent. The retention times were 0.45 and 3.5 min for Sb(V) and Sb(III), respectively. The hydrides were generated on-line with 3% m/v NaBH4 and 2 mol l−1 HNO3 aqueous solutions. The intensity of emission was linearly related to the concentration of the Sb(V) species in the range 1.0–50.0 µg l−1 (r2 = 0.9976) and of Sb(III) in the range 3.0–200 µg l−1, with detection limits of 0.8 and 1.9 µg l−1, for Sb(V) and Sb(III), respectively. The precision evaluated using the relative standard deviation (RSD) was 4.4 and 2.5% (n = 10) for Sb(V) and Sb(III) at concentrations of 10 µg l−1, respectively. The method has a sensitivity suitable for monitoring drinking and surface water according to the regulations established by the EU directives for antimony (10 µg l−1) and has been applied to the speciation of inorganic antimony in several spiked water samples.
