A novel method for prevention of the oxidation of Sb(III) during sample pretreatment, preconcentration of Sb(III) and Sb(V) with nanometer size titanium dioxide (rutile) and speciation analysis of antimony, has been developed. Antimony(III) could be selectively determined by flow injection-hydride generation-atomic absorption spectrometry, coexisting with Sb(V). Trace Sb(III) and Sb(V) were all...

A new visual colorimetry for trace antimony(V) based on ion-pair solid-phase extraction to a PTFE-type membrane filter with bis[2-(5-chloro-2-pyridylazo)-5-diethylaminophenolato]cobalt(III) ion ([Co(5-Cl-PADAP)(2)](+)) has been developed. Experiments showed that hexachloroantimonate(V) ion (SbCl(6)(-)) was adsorbed with [Co(5-Cl-PADAP)(2)](+) to the front surface of the PTFE filter. The adsorpt...

The migration of antimony (Sb) from polyethylene terephthalate (PET) bottling for acidic juices have been assessed in this study. Inductively coupled plasma mass spectrometric (ICP-MS) method was chosen for antimony content determination. Experiments were undertaken at different conditions (15, 25, 35, 45days at 25, 50°C for first use bottle, reused bottle). Two different acidic juices (lemon j...

This paper presents statistical analysis of results of determination of the total content of arsenic, antimony, selenium and microcomponents in 49 samples of groundwater from an area of western Poland (Wielkopolska). The total content of arsenic reached up to 3.00 ng/ml, antimony 1.25 ng/ml, selenium < 0.15 ng/ml, at detection limits of 0.16 ng/ml for As, 0.18 ng/ml for Sb and 0.15 ng/ml for Se...
