Coprecipitation of cobalt(II) with zinc(II) 8-hydroxyquinolate

Neptunium(V) Coprecipitation with Calcite

Coprecipitation experiments of Np(V) and U(VI) with calcite were performed in mixed-flow reactors under steady state conditions at room temperature for up to 400 h at precipitation rates of 1.0 × 10-8 to 6.8 × 10-8 mol/(m2 s). The saturation index with respect to calcite varied between 0.04 and 0.95. Initial Np(V) or U(VI) concentrations were 1 μmol/L, 0.01 mol/L NaCl was used as background ele...

Theoretical study on the electron transfer and phosphorescent properties of iridium(III) complexes with 2-phenylpyridyl and 8-hydroxyquinolate ligands.

The complexes AlQ(3) and Ir(ppy)(3) (Q = 8-hydroxyquinolate; ppy = 2-phenylpyridyl) are typical green emitting fluorescence and phosphorescence materials, respectively. Here we hybridize Ir(ppy)(3) with AlQ(3) to investigate the optoelectronic properties of the Ir(III)-centred derivatives including (ppy)(2)IrQ, (ppy)IrQ(2) and IrQ(3) by using density functional methods. Our calculations show th...

Chloritization of Montmorillonite by Its Coprecipitation with Magnesium Hydroxide

A magnesium hydroxide-montmorillonite complex prepared at an OH/Mg molar ratio of 2 (16 meq Mg/g clay) and immediately cleaned of any free Mg(OH)2 behaves like magnesium-chlorite and shows no change during 3 months ageing. Magnesium hydroxide completely precipitates within the interlayer space of montmorillonite. X-ray diffraction analysis, thermal (DTA and TGA) studies, i.r. absorption analysi...

Removal of Arsenic by Direct Coprecipitation Filtration

Ammonium sulfate coprecipitation antibody determination with purified staphylococcal enterotoxins.

The ammonium sulfate coprecipitation technique of Farr was applied in a study of the purified enterotoxins of Staphylococcus aureus. Ammonium sulfate coprecipitation of iodine-131-labeled enterotoxins A, B, and C, with the use of a 1.6 m concentration of (NH(4))(2)SO(4), revealed differences in the antigen-binding capacity of normal and immune rabbit sera for the enterotoxins. The coprecipitati...
