Abstract The present work is dedicated to the very important area of analytical chemistry—extraction- photometric determination of ions from a solid phase. We carried out studies on the extraction of nickel picrate (NiPik2) from the solid phase using solutions of tetrahalobicyclic reagents of the acetylene series with a dicarbonyl bridge in the side chain (L1, […]
Abstract Mono-, bi- and trinuclear carbinol derivatives of ferrocene C5H5FeC5H4-C(CH3)2OH (I), [C5H5FeC5H4]2C(CH3)OH (II), [C5H5FeC5H4]3C-OH (III) were synthesized. the thermal stability and thermodynamics of the pyrolysis of these compounds have been studied. The composition and structure of the synthesized compounds were established by elemental analysis (AAS, C, H analysis), 1H NMR, IR, and UV/visible spectroscopy. In […]
Abstract The work demonstrated that hydrazide of maleic and hydrazine diacetic acid(L-2,2'-(2-(3- carboxyacryloyl)hydrazine-1,1-diil)diacetic acid) forms mononuclear complexes [CuL(H2O)2] and [VОL(H2O)2]. The structure and physical properties of these complex compounds have been studied by IR, UV spectroscopy and thermogravimetric methods of analysis. On the basis of the data obtained, the structure of the complexes was proposed, […]
Abstract This article presents for the first-time the sulfated chitosan (SCS), synthesized on the basis of chitin/chitosan obtained from cysts of the Karakalpak population of Artemia parthenogenetica of the Aral Sea, and some of its physicochemical characteristics. Structural studies of chitin/chitosan and SCS were carried out by infrared spectroscopy. The IR spectrum data showed amide […]
Abstract Self-assembled nanoparticles are an area of great research prospect as they offer switchable element for designing and creating micro-scale constructs. Self-assembly of nano-hybrids through some non- covalent interactions such as electrostatic, π-π and van der Waal interactions in different classes of composite materials provide a great prospect of utilization of these functional properties in […]
Abstract This article includes thorough information on the synthesis process and physicochemical properties of the products generated from the reaction of dodecanoic acid and ethane-1,2-diamine IR spectroscopy was used to confirm the structure and composition of the reaction products. Several parameters of the obtained surfactants were distinguished, including surface tension, electrical conductivity, and petro-dispersing parameters. […]
Abstract Sb2S3 is stable under environmental conditions and a promising semiconductor material for optoelectronic applications, its potential capabilities in solar cells, photodetectors, and other devices are being investigated. It has an indirect-band gap of approximately 1.7-1.9 eV depending on the crystal structure which makes it suitable for absorption of visible light and its use in […]
Abstract Spectrophotometric methods are used to study the reaction of the nickel complex with 2.4- tyazolidindico (L) and its derivatives {5- (gasilysiliden) -2,4-tyazolidindio (L1), 5- (2-chlorbenzyliden) -2,4- tyazolidindion (L2), 5-(2-hydroxybenzylide) -2,4-tiazoleader (L3), 5- (4-hydroxybenzylide)-2,4- tyazolidindion(L4),5-(2-Brom-5-methoxybenzyiliden)-2,4-tiazolyidinedion (L5). With a single extraction, the chloroform is extracted by 97.8-98.4 % of the nickel. The study of the dependence […]
