the solvent extraction of gallium from a concentrated jajarm bayer process liquor containing 164.90 g/l of na2o, 86.70 g/l of al2o3 and 106.02 ppm of gallium was investigated using 10 vol.% kelex100, a 7-alkyl substituted-8 hydroxyquinoline as an extractant, 10 vol.% etanol as a modifier and kerosene as a diluent. at (vo :va = 1.0:1.0) organic to aqueous phase ratio and at room temperature, 93....

Gallium maltolate, tris(3-hydroxy-2-methyl-4H-pyran-4-onato)gallium (GaM), is an orally active gallium compound for therapeutic use. It is moderately soluble in water (10.7 +/- 0.9 mg/mL at 25 composite functionC) with an octanol partition coefficient of 0.41+/-0.08. The molecule is electrically neutral in aqueous solution at neutral pH; a dilute aqueous solution (2.5 x10-(-5) M) showed little ...

*Author for correspondence:rajan. [email protected] Aims: Increased 18F-flurodeoxyglucose uptake within active brown adipose tissue (BAT) on an 18F-flurodeoxyglucose PET/CT study is a known pitfall that has been well described in the literature. We have noted a similar phenomenon occurring in gallium-67 studies performed on neonates, which introduces an undesirable element of complexity when ev...

When cultured in a defined citrate medium supplemented with 1 mM gallium (III) Pseudomonas fluorescens ATCC 13525 experienced a lag phase of 40 h with no apparent diminution in cellular yield. Following initial uptake of the metal-ligand complex, gallium was secreted in the spent fluid. This lag phase was abolished either by inoculating the medium with gallium adapted cells or by inclusion of i...

introduction: despite widespread use of 67gallium for lymphoma evaluation, timing of imaging after injection is a matter of controversy and to the extent of our knowledge no direct comparison has been made between early and delayed gallium images. we aimed to compare 24 and 48 hours post injection planar gallium imaging for evaluation of lymphoma recurrence. methods: 255 patients suspicious of...

Modern medical microwave diagnostic equipment requires the use of solutions related to compactness developed devices and high performance. It is possible achieve set conditions with a modern semiconductor component base based on A3B5 compounds. The paper presents designs main control elements signal as part radiothermometer monolithic Al-GaN/GaN/SiC HEMT SPDT transistor switch MIC LNA basis pHE...

gallium extraction from jajarm bayer process liquor (jajarm, iran) was investigated using microemulsions. also the behavior of aluminum was studied as an impurity. kelex100 (4-ethyl, 1-methyl, 7-octyl, 8-hydroxyquinoleine), iso-decanol and n-butanol, and kerosene were used as the surfactant, co-surfactant, and oil phase, respectively. ternary phase diagrams were produced using various co-surfac...
