Erratum to: Flame atomic absorption spectrometric determination of trace amounts of Pb(II) and Cr(III) in biological, food and environmental samples after preconcentration by modified nano alumina

Erratum to: Microchim Acta

DOI 10.1007/s00604-010-0478-y

An error occured in the legend of Table 1. The correct legend of Table 1 is given below:

Table 1 Some of the band assignments of the infrared spectra for γ- Al₂O₃, DNPH-γ-Al₂O₃ and metal loaded DNPH-γ-Al₂O₃

An error occured in Tables 4 and 5. The corrected tables are given on the next pages.

Tables 4 and 5 should be as follow:

Table 4 Analytical results for the determination of Pb(II) and Cr(III) in real samples

Table 5 Comparative data from some recent papers on solid-phase extraction
