Depending on the pH of the matrix and the concentration of Sb(V), we observed that the atomic fluorescence emission due to Sb(V) could contribute up to 40% of the emission signal during the determination of Sb(III). This can cause significant errors in Sb speciation analyses. Besides, interferences from heavy metals such as Mn(II), Cu(II), Fe(III), Co(II) and Ni(II) can cause severe depression of...
