“…The concentrations of Sb(III) obtained in our study were compared with global concentrations of antimony in different water samples ( Table 6 ). As seen, the levels of Sb(III) obtained in this study were comparable with those reported elsewhere [ 50 , 54 , 55 ]. However, they were found to be higher than those reported in Algeria, Mexico and Brazil ( Table 6 ).…”

Antimony(III) is a rare element whose chemical and toxicological properties bear a resemblance to those of arsenic. As a result, the presence of Sb(III) in water might have adverse effects on human health and aquatic life. However, Sb(III) exists at very ultra-trace levels which may be difficult for direct quantification. Therefore, there is a need to develop efficient and reliable selective extraction and preconcentration of Sb(III) in water systems. Herein, a selective extraction and preconcentration of trace Sb(III) from environmental samples was achieved using ultrasound assisted magnetic solid-phase extraction (UA-MSPE) based on magnetic Sb(III) ion imprinted polymer-Fe3O4@SiO2@CNFs nanocomposite as an adsorbent. The amount of antimony in samples was determined using inductively coupled plasma optical emission spectrometry (ICP-OES). The UA-MSPE conditions were investigated using fractional factorial design and response surface methodology based on central composite design. The Sb(III)-IIP sorbent displayed excellent selectivity towards Sb(III) as compared to NIIP adsorbent. Under optimised conditions, the enrichment factor, limit of detection (LOD) and limit of quantification (LOQ) of UA-MSPE/ICP-OES for Sb(III) were 71.3, 0.13 µg L−1 and 0.44 µg L−1, respectively. The intra-day and inter-day precision expressed as relative standard deviations (%RSDs, n = 10 and n = 5) were 2.4 and 4.7, respectively. The proposed analytical method was applied in the determination of trace Sb(III) in environmental samples. Furthermore, the accuracy of the method was evaluated using spiked recovery experiments and the percentage recoveries ranged from 95–98.3%.

“…Many miniaturized techniques such as homogenous liquid-liquid microextraction [ 22 , 23 ], solid phase extraction technology [ 24 – 26 ], cloud point extraction [ 2 , 27 ], single drop microextraction [ 28 – 30 ], hollow-fiber liquid phase microextraction [ 17 , 31 ], and dispersive liquid phase microextraction [ 32 , 33 ] have been used as the processing methods of preconcentration. Also, these methods have been applied to preconcentration of antimony species.…”

A new sensitive method for antimony (III) determination by graphite furnace atomic absorption spectrometry (GFAAS) has been developed by using N-benzoyl-N-phenylhydroxylamine (BPHA) and 1-butyl-3-methylimidazolium hexafluorophosphate ([C4mim][PF6]) single drop microextraction. The single drop microextraction (SDMM) system is more competitive compared with other traditional extraction methods. Under the optimized conditions, the limit of detection (signal-to-noise ratio is 3) and the enrichment factor of antimony (III) are 0.01 μg·L−1 and 112, respectively. The relative standard deviation of the 0.5 μg·L−1 antimony (III) is 4.2% (n=6). The proposed method is rather sensitive to determinate trace antimony (III) in water.
