    The separation of germanium tetrachloride from arsenic trichloride by fractional distillation For reproduction of material from all other RSC journals and books: The separation of germanium tetrachloride from arsenic trichloride by fractional distillation. Determination of Silicon, Phosphorous, Arsenic, and Germanium as Heteropoly Acids Article in Journal of Analytical Chemistry 58(9) September with 34 Reads How we measure 'reads'.

    Abstract. A method for the separation of carrier-free arsenic from bulk amount of germanium has been developed. 74,73 As has been produced through the reaction nat Ge(p,xn) 47,73 As with 13 MeV protons obtained from Variable Energy Cyclotron, Calcutta. The separation is performed by the distillation of Ge followed by anion exchange separation of As(V) using Dowex 1×8 anion exchange by: The results are presented of a study of the behaviour under uniaxial compression of absorption lines due to transitions from the ground state manifold of states of arsenic impurities in germanium to excited p states. It is found that the shear deformation potential constant Ell of the excited p states and conduction band minima of germanium is 164±02 eV. The equivalent deformation Cited by: 3.

    Germanium (Ge) is considered a critical element due to its many industrial applications; Ge is a metalloid used in solar cells, fiber optics, metallurgy, chemotherapy, and polymerization catalysis. The main sources of Ge are sulfides ores of Zn, Pb, and Cu, coal deposits, as well as by-products and residues from the processing of these ores and coals (e.g., smelting flue dust and coal fly ashes).Cited by: 3.

About Germanium Arsenide. Germanium Arsenide is a crystalline solid used as a semiconductor and in photo optic applications.

American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade. A simple, rapid, accurate, and reliable method of simultaneous determination of arsenic, germanium, phospohrus, and silicon is reported.

The method involves first, the determination of germanium as the phenylfluorone complex and its selective extraction with isoamyl by: 4. Arsenic and selenium speciation using HPLC–ICP–MS.

ICP–MS has revolutionised quantitative analysis of arsenic and selenium in rice grain. Efficient ionisation in the plasma results in high sensitivity enabling analysis even at the trace (μg L –1) levels found in uncontaminated rice grain, and the multi-element capability of the ICP–MS facilitates the identification of relationships Cited by:   Separation of molybdoheteropoly acids of phosphorus, arsenic, silicon and germanium as ion-associates by HPLC.

For example, Kraak and Walz [Kra65] reported electrophoretic separation of americium and curium from a solution containing M EDTA in a 4-h run, while Bächmann [Bäc66] has reported separation of actinium, americium, and curium from one another, as well as separation of various mixtures of actinides and lanthanides.

The uranium is eluted in ml, with a l/K nitric acid-ether eluent, and the thorium is eluted with a 12,5^ nitric acid-ether eluent.

Keaber (10) demonstrated a similar separation on a cellulose column. Cellulose columns with ether.Quantitative analysis with HPLC-ICPMS under gradient elution conditions with increasing content of organic solvents is severely restricted because the elemental response can vary significantly with the amount of carbon reaching the plasma.

The present work offers a solution to this challenge to elemental species quantification by introducing a volatile organic solvent directly into the spray.
