In this regard, we synthesized CoTe2 and CoSe2 nanostructures via an anion-exchange-reaction between pre-synthesized Co(OH 2 hexagonal nanosheets and chalcogen (tellurium and selenium) ions under hydrothermal conditions.
These are manganese, silicon, aluminum, nickel, chromium, cobalt, molybdenum, vanadium, tungsten, titanium, niobium, zirconium, nitrogen, sulfur, copper, boron, lead, tellurium, and selenium.
However, indium, tellurium, and selenium are relatively scarce.
These includes the cation of cadmium, mercury and/or zinc combined with anionic metals, like sulfur, tellurium, and selenium.
But tin and lead belong to the same group in the periodic table, and tellurium and selenium both are members of another group.
12), Z = 3, with Bi located at 6c (0 0 z) Wyckoff site and the two types of tellurium and selenium, Te1/Se1 at 3a (0 0 0) positions and Te2/Se2 at 6c. Calculated profiles present an excellent agreement with the experimental data (Fig. 1b).
To determine the total tellurium and selenium in the samples, first Te (VI) and Se (VI) were reduced to Te (IV) and Se (IV), and then the microextraction method was performed.
A simple and effective speciation and preconcentration method based on hollow fiber liquid phase microextraction (HF-LPME) was developed for simultaneous separation of trace inorganic tellurium and selenium in environmental samples prior to electrothermal atomic absorption spectroscopy (ETAAS) determination.
Tellurium and selenium compounds are similar.
These are formed by oxidizing mixtures of tellurium and selenium with or.
