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 ...
Green catalytic processing of native and organosolv lignins
Two ways of catalytic depolymerization of native and isolated wood lignins are described: the peroxide delignification of hardwood (aspen, birch) and softwood (abies) in the medium of acetic acid – water over TiO2 catalyst ...
Effect of Electric Field on Ion Transport in Nanoporous Membranes with Conductive Surface
The effect of an external electric field on the ionic conductivity and selective properties of ceramic membranes based on alumina nanofibers coated with a conductive carbon layer has been studied. It has been shown that ...
Production and properties of bacterial cellulose by the strain Komagataeibacter xylinus B-12068
A strain of acetic acid bacteria, Komagataeibacter xylinus B-12068, was studied as a source for bacterial cellulose (BC) production. The effects of cultivation conditions (carbon sources, temperature, and pH) on BC production ...
