The determination of Sb(III) and Sb(V) was based on the efficiency of hydride generation employing NaBH4, with and without a previous KI reduction, using proportional equations corresponding to the two different measurement conditions. The extraction efficiency of total antimony and the stability of Sb(III) and Sb(V) in different extraction media (nitric, sulfuric, hydrochloric, acetic acid, methanol and ethanol) were evaluated. Results demonstrated that, based on the extraction yield and the stability of extracts, 0.5 mol L− 1 H2SO4 proved to be the best extracting solution for the speciation analysis of antimony in mushroom samples. The limits of detection of the developed methodology were 0.6 and 1.1 ng g− 1 for Sb(III) and Sb(V), respectively. The relative standard derivation was 3.8% (14.7 ng g− 1) for Sb(V) and 5.1% (4.6 ng g− 1) for Sb(III). The recovery values obtained for Sb(III) and Sb(V) varied from 94 to 106% and from 98 to 105%, respectively. The method has been applied to determine Sb(III), Sb(V) and total Sb in five different mushroom samples; the Sb(III) content varied from 4.6 to 11.4 ng g− 1 and Sb(V) from 14.7 to 21.2 ng g− 1. The accuracy of the method was confirmed by the analysis of a certified reference material of tomato leaves.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2013-10-08T16:38:09Z No. of bitstreams: 1 1-s2.0-S0584854709000755-main.pdf: 202450 bytes, checksum: 21d854a51b5504b60d7b28d426669191 (MD5)Made available in DSpace on 2013-10-08T16:38:09Z (GMT).
