ПРИМЕНЕНИЕ СИЛИКАГЕЛЯ, ХИМИЧЕСКИ МОДИФИЦИРОВАННОГО СЕРОСОДЕРЖАЩИМИ ГРУППАМИ, ДЛЯ РАЗДЕЛЕНИЯ И ОПРЕДЕЛЕНИЯ ПЛАТИНЫ И РЕНИЯ В КАТАЛИЗАТОРАХ НА ОСНОВЕ ОКСИДА АЛЮМИНИЯ
Adsorbents based on silica chemically modified by sulfur-containing groups (dithiocarbamate, thiodiazolethiol, mercaptophenyl, and aminobenzothiazole) quantitatively extract (recovery ≥99%) platinum( IV) from solutions ...
Extraction of precious metals from industrial solutions by the pine (Pinus sylvestris) sawdust-based biosorbent modified with thiourea groups
A novel biosorbent based on pine (Pinus sylvestris) sawdust with chemical grafted thiourea groups was proposed for preconcentration of precious metals. A simple procedure was proposed for the synthesis of biosorbent ...
Separation and preconcentration followed by ICP-OES and ICP-MS determination of precious metals using silica gel chemically modified with dithiocarbamate groups
Silica gel chemically modified with dithiocarbamate groups (DTCS) was used for separation and preconcentration of precious metals and their subsequent determination in geological samples and their processing products by ...
Application of evolutionary rietveld method based XRD phase analysis and a self-configuring genetic algorithm to the inspection of electrolyte composition in aluminum electrolysis baths
The technological inspection of the electrolyte composition in aluminum production is performed using calibration X-ray quantitative phase analysis (QPA). For this purpose, the use of QPA by the Rietveld method, which does ...
Structure of bis(2-Thiobarbiturate)Tris (2,2-Bipyridyl)Nickel(II) Hexahydrate
The [Ni(Bipy) 3 ](Htba) 2 ·6H 2 O (I) complex (Bipy is 2,2′-bipyridyl, H 2 tba is 2-thiobarbituric acid) is synthesized and its structure is determined by single crystal XRD (cif-file CCDC No. 1836529). The crystals of I ...
