Aluminum Fractionation in the Water of Karakaya Dam Lake (Malatya, Turkey)
Aluminum speciation and fractionation atomic absorption spectroscopy enrichment trace element
2010/4/21
A method was developed for the determination of trace amounts of Al species in water samples using the amberlite type XAD-4 resin. For this purpose, total dissolved Al, organically bonded Al and parti...
Increasing temperature decreases aluminum concentrations in Central European lakes recovering from acidification
Increasing temperature decreases aluminum concentrations Central European lakes recovering acidification
2014/5/22
As acidic water percolates through mineral soils, Al is mobilized and transported into streams and lakes. We evaluate the effect of increasing temperature (climate warming) on Al concentrations in fou...
The Effects of Benzoic Acid in Chloride Solutions on the Corrosion of Iron and Aluminum
Effects Aluminum the Corrosion of Iron
2010/4/22
In this work, the corrosion behavior of iron and aluminum was investigated in 0.1 M NaCl solutions with an initial pH value of 8 and containing various concentrations (0, 30, 150, 300 ppm) of benzoic ...
Effect of Kaolinite and Sulfate on the Formation of Hydroxy-Aluminum Compounds
Bayerite CMS Clay KGa-2 Gibbsite Hydroxysulfate Noncrystalline Compounds Nordstrandite
2011/12/2
Abstract: OH-Al solutions were prepared by adding appropriate amounts of NaOH to AlCl3 to obtain OH/Al mole ratios of 2.0, 2.5, 2.7, 3.0, and 3.3 in the final suspension. Solid Na2SO4 and Georgia kaol...
Phosphorus inactivation by aluminum in the water column and sediments: Lowering of in-lake phosphorus availability in an acidified watershed-lake ecosystem
Phosphorus inactivation aluminum in the water column sediments in-lake phosphorus availability acidified watershed-lake ecosystem
2014/6/17
Acid precipitation has been shown to reduce phosphorus (P) outputs from terrestrial sources. We present field evidence that the in-lake P cycle may also be disrupted in atmospherically acidified water...

Oligomeric but not monomeric silica prevents aluminum absorption in humans
Oligomeric silica monomeric silica, orthosilicic acid silicon silicic acid silica aluminum absorption, bioavailability gastrointestinal uptake accelerator mass spectrometry
2016/6/3
Background: Soluble silica, a ubiquitous component of the diet,
may be the natural ligand for dietary aluminum and may prevent
its accumulation and toxicity in animals. However, previous
studies on...
Oxygen-Isotope Fractionation between Aluminum-Hydroxide Phases and Water at <60C: Results of Decade-Long Synthesis Experiments
Aluminum Hydroxides Fractionation Factor Gibbsite Oxygen Isotope Synthesis
2011/12/6
Abstract: Oxygen-isotope data were obtained for synthetic aluminum-hydroxide phases precipitated over 65–125 mo and have been compared to results from similar experiments conducted for 3–56 mo. The Al...
