TL;DR: In this paper, a gel-sol method for the synthesis of monodispersed particles was applied in the preparation of uniform basic aluminum sulfate microcrystals of different shapes including round-cornered cubes, sharp-edged cubes, truncated-corner cubes, hexagonal platelets, and ellipsoids.

TL;DR: In this article, the performance of rice husk char (RHC) was compared with other low-cost adsorbents for their aluminium removal capacity, and the effect of pH, initial concentration, contact time and temperature was studied for adsorption of aluminium from water under batch conditions.
Abstract: Aluminium is one of the trace inorganic metals present in drinking water. High aluminium concentrations (3.6 to 6 mg/l) may precipitate as aluminium hydroxide affecting aquatic life. Aluminium is also a suspected agent of neurological disorders such as Alzheimer’s disease and senile dementia. The present investigation aims at the sorption of aluminium from drinking water using a low-cost adsorbent. Rice husk char and activated rice husk char were prepared and characterised for various physicochemical properties. The performance of rice husk char (RHC) was compared with other low-cost adsorbents for their aluminium removal capacity. The effect of pH, initial concentration, contact time and temperature was studied for adsorption of aluminium from water under batch conditions. The maximum adsorption capacity was observed with rice husk char at an optimal pH of 4.2. The adsorption of aluminium follows the Freundlich adsorption isotherm. The rate of aluminium adsorption was successfully described by a first-order kinetic model. The thermodynamic study revealed that aluminium adsorption is an exothermic process and the adsorption decreases with an increase in temperature.

TL;DR: It has been found that low quantities of protein tend to cross-link and aggregate the small Alhydogel clusters, in a more pronounced manner than high protein concentrations, and future exploitation of this treatment of Alhydrogel is likely to be of immediate value for more efficient vaccine production.

TL;DR: Although in this study aluminium hydroxide was given at doses higher than those usually consumed by pregnant women, no signs of maternal or developmental toxicity were observed when the compound was given alone or concurrently with high doses of ascorbic acid.
Abstract: The present study was conducted to assess if the concurrent ingestion of high doses of aluminium hydroxide and ascorbic acid might result in maternal and developmental toxicity in mice. Three groups of pregnant Swiss mice were given by gavage daily doses of aluminium hydroxide (300 mg/kg), ascorbic acid (85 mg/kg), or aluminium hydroxide (300 mg/kg) concurrent with ascorbic acid 85 (mg/kg) on gestational days 6-15. A fourth group of animals received distilled water and served as control group. Dams were killed on gestation day 18 and foetuses were examined for external, internal, and skeletal abnormalities. The reproductive data did not show embryotoxic or foetotoxic effects in any group. No gross, internal, or skeletal malformations or variations related to the different treatments were found. There were no significant differences between control and treated groups on the aluminium levels in maternal liver and bone as well as in whole body foetuses, whereas aluminium concentrations were significantly higher in placenta and kidney of dams receiving aluminium hydroxide and aluminium hydroxide plus ascorbic acid than in those from the control group. Although in this study aluminium hydroxide was given at doses higher than those usually consumed by pregnant women, no signs of maternal or developmental toxicity were observed when the compound was given alone or concurrently with high doses of ascorbic acid.

TL;DR: The potentiometric determination of the formal hydrolysis ratio based on an automated alkaline titration procedure has been described and the results have been cross-verified by quantitative 27Al solution nuclear magnetic resonance (27Al NMR) measurements.
