AI Article Synopsis
- Flow-injection analysis (FIA) using fluorescence detection and lumogallion was utilized to analyze aluminum species in soil extracts following separation with ionic exchangers.
- Aluminum can be categorized into three groups: Al3+ along with Al-OH complexes, aluminum-organic complexes, and anion species, by employing both strongly and weakly acidic cation exchangers at pH 5.
- A significant portion of water-soluble aluminum in soils exists as complexes with humic substances, indicating their interaction with organic material.
Article Abstract
Flow-injection analysis (FIA) with fluorescence detection of aluminum using lumogallion was applied to the chemical speciation of aluminum in soil extracts after the separation of aluminum species with ionic exchangers. Aluminum complexes with organic substances (anion species) can be specified from other species by using a strongly acidic cation exchanger in the pH range of 3 to 5. Furthermore, aluminum can be separated into three categories, namely, (i) the Al3+ and Al-OH complex, (ii) aluminum organic complexes (cation species), and (iii) its anion species by using a strongly acidic and a weakly acidic cation exchanger at around pH 5. A considerable percentage of water-soluble aluminum in soils was found to be complexes with humic substances.

Mining activities have led to significant rare earth elements (REEs) contamination and ecotoxicological risks in aquatic systems. However, the concentration, speciation, and primary controlling factors of REEs in aquatic systems in southwest China have remained unclear. This study investigated the water geochemistry, concentration, speciation, fractionation patterns, and anomalies of REEs in the surface water, shallow groundwater, and deep groundwater within a mining-impacted catchment area in southwest China across different seasons.

The paper provides a summary of findings regarding the composition of the fine fraction of incineration bottom ash. While the recovery of metals is common practice for particles larger than 2 mm, it has been less common for finer particles, despite them constituting 30-40 % of the overall bottom ash mass flow. Detailed knowledge of the material composition of this fraction is essential for successful metal recovery.

This work reports on the first solvate ionic liquids (SILs) based on aluminium(III) and gallium(III) triflates, M(OTf), and triglyme (G3). Liquid-phase speciation of these new SILs was studied by multinuclear NMR spectroscopy. Across the compositional range of G3 : M(OTf) mixtures, both metals were found to be in a hexacoordinate environment, with both G3 and [OTf] ligands present in the first coordination sphere, and apparently exchanging through a dynamic equilibrium.

Article Synopsis
- * A recent study (2015-2022) found that 80% of sampled sites had aluminum concentrations exceeding safe levels, with increasing trends observed at large sampling locations.
- * The research utilized a Bayesian model to analyze factors affecting aluminum levels and offers a predictive tool for monitoring and potentially mitigating aluminum toxicity in freshwater ecosystems.

Antimony (Sb) pollution in surface water and soil has earned extensive attention. Our previous study synthesized a new class of alumina supported Fe-Mn binary oxide (Fe-Mn@AlO) and found that MnO in the composite oxidized Sb(III) to Sb(V) and FeOOH and AlO played an indispensable role in adsorption of Sb(III) and Sb(V). This study further explored the removal of Sb in surface water and in situ sequestration of Sb in Sb-contaminated field soil via Fe-Mn@AlO.
