“…In the case of aluminum, the solid sorbents were mainly applied for its preconcentration and separation from the matrix components. For this purpose chelating resins with iminodiacetate functional groups such as Chelex 100 [14] or Duolite ES446 [15], and poly-(dithiocarbamate) resin (PDTG) [16] or oxine-cellulose [17] were used. Also anion exchange resins or non-ionic sorbents modified with chelating ligands [18][19][20] and commercial cation exchangers [21] were used.…”

Various microcolumns with solid sorbents (ion exchange resins, functionalised cellulose sorbents, chelating resins) have been tested with respect to their ability for the purification of aluminum contaminated chemicals used as modifiers in electrothermal atomic absorption spectrometry. The purification of NaNO(3), Mg(NO(3))(2), K(2)SO(4) and (NH(4))(2)HPO(4) has been the most effective with an almost 100% efficiency, when Spheron-Oxine was used as chelating resin. The sorption of aluminum from KOH solution has been found to be very high (around 90%) for all investigated sorbents. However, the best results have been obtained with anion-exchange resins. It has been difficult to purify concentrated mineral acids (HCl, H(2)SO(4)). A retention of aluminum above 80% has been achieved only when Cellex P, Chelex 100 or Amberlite XAD-2 have been used.
