“…Water samples from three reservoirs, Cixerri, Simbirizzi, and Bau Pressiu, and their respective treatment plants were collected, respectively, on four, four, and "ve sampling dates over the October 1995}February 1996 period. Samples were collected in high-density polyethylene containers leached with 10% (v/v) nitric acid for 48 h (Fairman et al, 1994). The samples were brought to the laboratory immediately and the speciation procedure was performed.…”

“…16 In the present study, this method was adopted for determining free forms of aluminum in urine (labile monomeric ions). The modifications included that the ionic composition of the analytical column for fractionation be in the Na+ form instead of the H+ form; small samples were used for the ion-exchange procedure and a later analysis.…”

A procedure has been developed for the speciation of aluminum in urine samples of four normal subjects fed required diet on two dates. Three fractions of aluminum species, i.e., labile monomeric ions, non-labile monomeric ions along with labile complexes, and non-labile complexes were classified and determined by the combination of ion-exchange (IE), fluorometric spectrometry and graphite-furnace atomic absorption spectrometry (GF-AAS) techniques. The results showed that the aluminum in urine was mainly in non-labile complex forms.

“…In fact, several reports have been published comparing distinct and diverse methodologies, all of which seem to come to the conclusion that most of today's methods give an adequate and comparable estimation of what can be loosely called the "labile monomeric" or "toxic" aluminium fraction in waters [7,9]. The main reported drawback of all these method performance programs is the inevitable instability of any standard samples provided for the testing program.…”

A flow injection mini-column system based on short reaction times with 8-hydroxyquinoline (oxine) with ICP-AES detection is described for the isolation and preconcentration of the "fast reactive" or "toxic" aluminium fraction in water samples. Using a 3 s reaction time with oxine (5 × 10 -4 mol/l) at pH 5.0, the "fast reactive" aluminium fraction is shown not to include the non-toxic AlF 2+ species at low F -: Al 3+ molar ratios (0.3 : 1). The complexed aluminium is isolated in a stable and recoverable form on mini-columns of Amberlite XAD-2 (0.3 cm × 5.0 cm, resin particle size range 0.08 mm-0.16 mm)). The retained aluminium is recovered by "back-flushing" the analytical column with 1 mol/l HCl for final element specific detection by ICP-AES. Detection limits (after preconcentration) of 2 µg/l, a linear range of 0-500 µg/l, and possible preconcentration factors of up to 18 times are demonstrated with the present system. Implications for the possible solution of sample stability problems encountered with labile aluminium species analysis and the development of a "field sampling" technique are discussed, where the desired Al fraction is quantitatively retained in a stable form on mini-columns.
