24 Aluminum coagulants are widely used in water treatment plants to remove turbidity and 25 dissolved substances. However, because high aluminum concentrations in treated water are 26 associated with increased turbidity and because aluminum exerts undeniable human health 27 effects, its concentration should be controlled in water treatment plants, especially in plants 28 that use aluminum coagu...

Aluminum, the most abundant neurotoxic metal in our biosphere, has been implicated in the etiology of several neurodegenerative disorders including Alzheimer's disease (AD). To further understand aluminum's influence on gene expression, we examined total messenger RNA levels in untransformed human neural cells exposed to 100 nanomolar aluminum sulfate using high density DNA microarrays that int...

Correlation between the pathogenicity of certain staphylococci and their ability to produce coagulase has led to extensive studies of the clotting enzyme. Walston (1935) precipitated the clotting substance from cell-free filtrates of appropriate staphylococcal cultures by the use of ethanol, acetic acid, or ammonium sulfate. Walker et al. (1948) partially purified staphylocoagulase by repeated ...

Soil amendment is one of the most effective methods to improve saline-alkali soil. In this study, laboratory experiments were conducted verify effect 13 kinds amendments and their combinations (Citric acid (NM), Phosphogypsum (LS), Aluminum sulfate+citric (AL+NM), sulfate+phosphogypsum (AL+LS), acid+phosphogypsum (HH), Zeolite (Z), Acidified zeolite (ZH), sulfate (AL), sulfate+zeolite (AL+Z), s...

Many neurological diseases, including autism, depression, dementia, anxiety disorder and Parkinson’s disease, are associated with abnormal sleep patterns, which are directly linked to pineal gland dysfunction. The pineal gland is highly susceptible to environmental toxicants. Two pervasive substances in modern industrialized nations are aluminum and glyphosate, the active ingredient in the herb...

Aluminum is a significant impurity in the ion-adsorption rare earth ore. The changes occurrences of aluminum have great influence on leaching In this paper, column method was employed using magnesium sulfate as agent to investigate effects pH and concentration earths. results show that at low concentrations, earths greatly enhanced, while not significantly affected by decrease agent. At high sl...

Mesoporous aluminum oxyhydroxides composed of nanoflakes were prepared via a water-in-oil microemulsion-assisted hydrothermal process at 50 °C using aluminum salts as precursors and ammonium hydroxide as a precipitating agent. The microstructure, morphology, and textural properties of the as-prepared materials were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM)...

Metallic gallium dissolves slowly in dilute mineral acids but rapidly in aqua regia and concentrated sodium hydroxide. In its compounds, the valency is +3. Its oxygen compounds resemble those of aluminum in that there are highand lowtemperature forms of Ga2O3 and two hydroxides, Ga(OH)3 and GaO·OH. Substances which lower the hydrogen ion concentration throw down a white gelatinous precipitate f...
