Adsorption-photometric and test-determination of copper in aqueous media using the oxides modified with polyhexamethylene guanidine and bathocuproinedisulfonic acid
Adsorbents based on aluminium, zirconium and titanium oxides sequentially modified with polyhexamethylene guanidine (PHMG) and bathocuproinedisulfonic acid (Batocuprsulfo) were proposed for the adsorption-photometric and ...
Adsorption-photometric determination of iron using silica with nitroso-R salt and nitroso-N salt functional groups
Adsorbents based on silica sequentially modified by polyhexamethylene guanidine and nitroso-R salt or nitroso-N salt are proposed for the preconcentration and adsorption-photometric determination of iron. It is shown ...
Using Silica Modified by Tiron for Metal Preconcentration and Determination in Natural Waters by Inductively Coupled Plasma Atomic Emission Spectrometry
A new adsorbent is synthesized on the basis of silica consecutively modified by polyhexamethylene guanidine and 4,5-dihydroxy-1,3-benzenedisulfonic acid (Tiron) for the group preconcentration of Fe(III), Al(III), Cu(II), ...
Separation and Determination of Fe(III) and Fe(II) in Natural and Waste Waters Using Silica Gel Sequentially Modified with Polyhexamethylene Guanidine and Tiron
Silica gel, sequentially modified with polyhexamethylene guanidine and pyrocatechin-3,5-disulfonic acid (Tiron), was suggested for sorption separation and determination of Fe(III) and Fe(II). It was found that quantitative ...
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 ...
