Head Tertykh Valentin Anatolievich, Registration Date 15-11-2011 Organization Zhytomyr State University named after Ivan Franko popup.description2 The objects of the research are chemically modified silicas with the covalently fixed 4 (2 pyridylazo) resorcinol, 1(2 pyridylazo)-naphthol. The aim of the study is the research of the physical chemical properties of the chelating chemically modified sorbent agents of different nature, particularly adsorptive characteristics regarding the ions of the heavy metals. The methods of the research are photometrical, atomic absorption spectrography, titrimetric analysis. The research studies the sorption properties of the chemically modified adsorbing materials, synthesized according to the single-stage Mannich reaction. The study also investigates the adsorbing properties of the synthesized chelating adsorbing materials depending upon the pH solution regarding the ions of the metals, in particular the ions Pb(ІІ), Cd(ІІ), Ni(II), Со(ІІ), Cu(II), та Fe(III); studies the sorption properties of the modified silicas with the chemically inoculated molecules 4 (2 pyridylazo) resorcinol (PAR) and 1-(2-pyridylazo)-2-naphthol (PAN) concerning the ions of metals in the dynamic conditions of the adsorption; gives the opportunity to determine the ions of metals from the aqueous solutions in the process of their joint presence and beforehand concentrating. Within the research the defense of the PH.D. thesis "The Application of the Aminomethylation Reaction for the Immobilization the Chelating Analytical Reagents on the Silicas Surface" in Chemistry Science took place; the work connected with the publication the tutorial book for the magistrates and carrying out the research within the students and magistrates' graduate works continues Product Description popup.authors Вознюк Володимир Іванович Кичкирук Ольга Юріївна Кусяк Наталія Володимирівна Прохорчук Олена Ульянівна Янович Ірина Володимирівна popup.nrat_date 2020-04-02 Close
