Aluminum chlorohydrate III: Conversion to aluminum hydroxide

Journal of Pharmaceutical Sciences, 1981
Bayerite, an aluminum hydroxide polymorph, readily forms when the hydroxyl to aluminum ratio of aluminum chlorohydrate is raised to 3 by titration with sodium hydroxide. Dilution of aluminum chlorhydrate solutions with water leads to the formation of gibbsite, another aluminum hydroxide polymorph. The mechanism of conversion in each instance is related

Microstructure of Aluminum Hydroxides and the Formation of Aluminum Dye Lakes

Journal of Pharmaceutical Sciences, 1984
The effect of processing variables on the type of aluminum hydroxide and the dye content of the resultant lakes were investigated. The solid-state structure of aluminum lakes in conjunction with the associated aluminum hydroxide was studied by electron microscopy, X-ray diffraction, and IR spectroscopy. The conditions under which the aluminum hydroxide

Acetaminophen–Aluminum Hydroxide Interaction in Rabbits

Journal of Pharmaceutical Sciences, 1983
Acetaminophen-aluminum hydroxide interaction was investigated in a crossover study using six rabbits. Blood samples were collected at various time intervals for up to 6 hr following the oral administration of acetaminophen alone or in combination with aluminum hydroxide. Aluminum hydroxide at a 40-mg/kg dose did not appear to affect the rate and extent

Lack of teratogenicity of aluminum hydroxide in mice

Life Sciences, 1989
The embryotoxic and teratogenic potential of aluminum hydroxide, a therapeutic drug used as an antacid and phosphate binder, was investigated in Swiss mice. Mated female mice were given by gavage daily doses of 0, 66.5, 133 or 266 mg/kg of A1 (OH)3 on gestation days 6 through 15 and killed on gestation day 18.

Coprecipitation of silica with aluminum hydroxide

Colloid and Polymer Science, 1977
The reaction between aqueous solutions of aluminum nitrate and sodium silicate was studied over a wide range of concentrations and pH values. Turbidity and precipitate volume measurements allowed solubility boundaries to be determined and the conditions to be defined for the formation of stable and unstable sols.

Amorphous aluminum hydroxide gels

Journal of Non-Crystalline Solids, 1986
Abstract The gelation of aluminum hydroxide sols obtained from aluminum-sec-butoxide in acidic media leads, depending on the conditions of preparation, to gels with a structure ranging from crystalline to amorphous to super-amorphous. A model for the structure of “super-amorphous” gels is presented to explain the observations.

Gelation of Aluminum Hydroxide Sols

Journal of the American Ceramic Society, 1987
The gelation of aluminum hydroxide sols obtained from aluminum sec‐butoxide has been studied as a function of the conditions of preparation, including pH, temperature, and time of aging. The preceding studies of Yoldas have been extended in more acidic conditions, up to a molar proportion of 1.12 HNO3 per Al(OC4H9)3.

Detoxification of endotoxin by aluminum hydroxide adjuvant

Vaccine, 2001
Langmuir adsorption isotherms of endotoxin and aluminum-containing adjuvants at pH 7.4 and 25 degrees C revealed that aluminum hydroxide adjuvant has a greater adsorption capacity (283 microg/mg Al) and adsorption coefficient (1.3x10(4) ml/miccrog) than aluminum phosphate adjuvant (3.0 microg/mg Al, 0.20 ml/microg).

Enhanced Phosphorus Locking by Novel Lanthanum/Aluminum-Hydroxide Composite: Implications for Eutrophication Control.

Environmental Science and Technology, 2017
Lanthanum (La) bearing materials have been widely used to remove phosphorus (P) in water treatment. However, it remains a challenge to enhance phosphate (PO4) adsorption capacity and La usage efficiency. In this study, La was coprecipitated with aluminum
