A Procedure for the Fractionation of Aqueous Aluminum in Dilute Acidic Waters
TL;DR: In this article, a procedure was developed for the fractionation of aqueous aluminum, which results in the determination of acid-soluble aluminum, non-labile monomeric aluminum and labile moneric aluminum.

‘Acid rain’, dissolved aluminum and chemical weathering at the Hubbard Brook Experimental Forest, New Hampshire
TL;DR: In the Hubhard Brook watershed, the water path length in the soil zone is the crucial factor in the state of acid rain neutralization, aluminum chemistry and chemical weathering as mentioned in this paper.

Gibbsite solubility and thermodynamic properties of hydroxy-aluminum ions in aqueous solution at 25°C
TL;DR: In this article, the first unified equilibrium experimental model of Al ion speciation in waters from pH 4 to 9 was presented, based on the standard Gibbs free energies of formation (ΔG°f).

Forms of Aqueous Aluminum in Acidified Catchments of Central Ontario: A Methodological Analysis
TL;DR: During spring snowmelt in the Muskoka–Haliburton region of central Ontario, very little polymeric and amorphous aluminum was found, and most of the inorganic monomeric fraction was in the fluoride complexes.
