Gallium Citrate Ga-67 is the citrate salt of the radioisotope gallium Ga 67. Although the mechanism is unknown, gallium Ga 67 concentrates in lysosomes and is bound to a soluble intracellular protein in certain viable primary and metastatic tumors and focal sites of inflammation, allowing scintigraphic localization. Ga-67 scintigraphy (GS) cannot differentiate between tumor and acute inflammation.

Abstract. Gallium(III) has been widely used as a diagnostic and therapeutic agent in clinics for the treatment of various diseases, in particular, Ga-based drugs have been exploited as antimicrobials to combat the crisis of antimicrobial resistance.The therapeutic properties of Ga(IIIIII
The manufacture of semiconductor materials containing gallium and indium requires the separation of these metals owing to their coexistence in the resources of these materials. In this work, solvent extraction of In(III) and Ga(III) from a hydrochloric acid solution by ionic liquids (ILs) was investigated to separate them. The ILs were synthesized by reacting organophosphorus acids (Cyanex 272 ...
GaAs. Gallium arsenide (GaAs) is a compound semiconductor: a mixture of two elements, gallium and arsenic. Gallium is a by-product of the smelting of other metals, notably aluminum and zinc, and it is rarer than gold. Arsenic is not rare, but it is poisonous. Gallium arsenide has been developed for use in solar cells at about the same time that ...

Gallium. Solid gallium is a blue-gray metal with orthorhombic crystalline structure; very pure gallium has a stunning silvery color. Gallium is solid at normal room temperatures, but as well as mercury, cesium, and rubidium it becomes liquid when heated slightly.
NAYAK and DEVI/Turk J Chem complete equilibration. Similarly, the acid concentration was also varied from 1.0 10 3 mol/L to 5.0 mol/L, keeping the gallium concentration at 1.0 10 3 mol/L and Cyphos IL 101 at 5.0 10 3 mol/L. From Figure
The structure of the hydrated gallium(III), indium(III), and chromium(III) ions has been determined in aqueous perchlorate and nitrate solutions by means of the large-angle X-ray scattering (LAXS) and extended X-ray absorption fine structure (EXAFS) techniques. The EXAFS studies have been performed over a wide concentration range, 0.005−1.0 mol·dm-3 (2.6 mol·dm-3 for chromium(III)), while ...
Abstract: The distribution equilibrium of gallium(III) between n-octylaniline dissolved in toluene and acidic aqueous succinate media has been investigated as a function of the con-centration of extractant in the organic phase and concentration of hydrogen ions and gal-lium(III) ions in the aqueous phase.
The distribution ratio of gallium and vanadium increased with increasing equilibrium pH of the aqueous phase, the concentration of the extractants and temperature. Gallium (III) and vanadium (IV) were predominantly extracted at low pHe and were completely separated from aluminum at …
