“…[1][2][3][4] Seip et al 5 have investigated two spectrophotometric procedures for determining various forms of aluminum in river and stream waters in connection with the investigations of the effects of acid rain in Norway. These methods employ ferron-orthophenanthroline 6 and pyrocatechol violet as chromogenic reagents.…”

“…The result for the analysis of tap water indicates that this method could have a potential for aluminium speciation in natural waters. The pyrocatechol violet spectrophotometric method is considered to give total monomeric aluminium including fluoro and organic complexes .8, 9 The graphite furnace atomic absorption spectrometric results give the total aluminium including colloidal and polymeric species. The liquid chromatographic result is slightly lower than the PCV value, which could be due to a systematic error between the two methods, or possibly because the chromatographic technique is not responding to all the monomeric forms.…”

A method is described for the determination of aluminium by hig h-performance ion chromatography followed by post-column derivatisation with 8-hydroxyquinoline-5-sulphonate and fluorescence detection at 512 nm (excitation at 360 nm). A short (50 mm) low-capacity cation-exchange resin column was used as the analytical column and 0.1 M K2S04, adjusted to pH 3.0, as the eluent. The calibration graph was linear from 5 to 10000 pg 1-1 of aluminium with a detection limit (30) of 1 pg I-'. Typical relative standard deviations were 3.4% at the 250 pg 1-1 level. No interference was observed from other commonly occurring metals and aluminium was successfully determined in a certified reference material (Monel Alloy) and in tap water.

“…Examples of such acid mine drainage conditions in the tropics of Australia include the legacy Rum Jungle, Mount Morgan, Mount Todd, and Cosmo Howley mine sites [2][3][4]. In this region, concentrations of dissolved Al in slightly acidic fresh surface waters are generally low ($10-30 mg L À1 ) [5][6], but acidic mine waters have been found to contain concentrations of up to 480 mg L À1 Al [2].…”

The influence of dissolved organic carbon (DOC) on the toxicity of aluminum (Al) at pH 5 (relevant to acid mine drainage conditions), to the tropical green hydra (Hydra viridissima), green alga (Chlorella sp.), and cladoceran (Moinodaphnia macleayi) was assessed. Two DOC sources, a natural in situ DOC in soft billabong water (SBW) and Suwannee River fulvic acid (SRFA) standard, were compared. The order of sensitivity of the test organisms to dissolved Al (0.1 µm fraction) was Hydra viridissima > Moinodaphnia macleayi > Chlorella sp. with DOC reducing dissolved Al toxicity most for Hydra viridissima. However, colloidal or precipitated Al may contribute indirectly to the toxicity for M. macleayi and Chlorella sp. The toxicity of dissolved Al was up to six times lower in test waters containing 10 mg L(-1) DOC (in the form of SRFA), relative to toxicity observed at 1 mg L(-1) DOC. In contrast, the toxicity of Al was up to two times lower in SBW containing 10 mg L(-1) DOC, relative to water containing 1 mg L(-1) DOC. The increased ability of SRFA in reducing Al toxicity was linked to its greater affinity for complexing Al compared with the in situ DOC. This has important implications for studies that use commercial standards of humic substances to predict Al toxicity in local environments. Speciation modeling demonstrated that Al(3+) and AlOH(2+) provided a strong relationship with toxicity. An empirical relationship is provided for each organism that can be used to predict Al toxicity at a given Al and DOC concentration.
