From Selenium- to Tellurium-Based Glass Optical Fibers

2014-6-18  From Selenium- to Tellurium-Based Glass Optical Fibers for Infrared Spectroscopies ... Fibers enabling to observe the CO2 absorption band spreading around 15 µm should be developed. Tellurium-based glasses, due to their atoms’ heaviness, can transmit light further in the infrared region up to 28 µm [14]. Therefore, the telluride glass ...

Selenium and Tellurium concentrations of

2012-4-1  Within this scope, we have developed a high precision analytical method for the simultaneous determination of selenium and tellurium concentrations from a single sample aliquot and various rock matrices, including ultradepleted peridotites. The technique employs isotope dilution, thiol cotton fiber (TCF) separation and hydride generation MC-ICP-MS.

Selenium and tellurium systematics of the Earth’s

Selenium and tellurium, like the highly siderophile elements, may constitute key tracers for planetary processes such as formation of the Earth’s core and the Late Veneer composition, provided that their geochemical behavior and abundances in the primitive upper mantle (PUM) are well constrained.

Determination of Selenium and Tellurium in Basalt

2009-6-1  Promising methods have been developed recently for the determination of selenium (Se) and tellurium (Te) in geological materials at ng g −1 and lower levels, using hydride generation‐inductively coupled plasma‐mass spectrometry. Here we report on a new isotope dilution‐hydride generation‐inductively coupled plasma‐mass spectrometry (ID‐HG‐ICP‐MS) method for the

Selenium, Tellurium and Polonium - ScienceDirect

1997-1-1  The main source of selenium and tellurium is the anode slime deposited during the electrolytic refining of copper. Selenium is also recovered from the sludge accumulating in sulfuric acid plants and from electrostatic precipitator dust collected during the processing of copper and lead.

Recovering selenium and tellurium from copper

The significant amount of selenium and tellurium present in copper refinery slimes often makes the recovery of these elements not only desirable, but economically viable. While a variety of processes have been developed to this end, some are more feasible because they recover greater values and are environmentally safer.

Selenium and Tellurium concentrations of

As for highly siderophile elements, selenium and tellurium may constitute key tracers for planetary processes such as formation of the Earth's core and the Late Veneer composition, provided that their geochemical behaviour and abundances in the primitive upper mantle (PUM) are constrained. Within this scope, we have developed a high precision analytical method for the simultaneous ...

Selenium, Tellurium and Polonium - ScienceDirect

1997-1-1  Selenium and tellurium share to a limited extent sulfur's great propensity for catenation (see allotropy of the elements, polysulfanes, halides, etc.). As found in preceding groups, there is a diminution in the stability of multiple bonds (e.g. to C, N, O) and a corresponding decrease in their occurrence as the atomic number of the group ...

Selenium and Tellurium. Selenium is an essential trace element related to sulphur. It has a similar chemistry as sulphur and forms a range of organo-selenium compounds. It also is an important element in modern day electronics as it can be a semi-conductor. It is essential for humans in form of selenocysteine, which forms the catalytic centre ...
