The sorption of mercury ions out of solutions and waste waters by clinoptilolite of Aydag deposit (Azerbaijan) has been studied. It has been established that the sorptional capacity of clinoptilolite towards the mercury ions rises with the increase of pH and reduction the size of particles. The experiments let us value positively the possibility of […]
Influence of various climatic zones of Azerbaijan on phisical-mechanical and heat-phisical properties of polyamide has been investigated. It established that introduction of technical carbon in the structure of glass filled polyamide considerably raises stability of polymeric composition against influence of external factors.
Sorption of cobalt by titanium-manganese containing sorbent from model solutions and industrial waste wasters in static condition at 20–65oC temperature and 5.0; 6.5 and 8.0 pH intervals has been analyzed. The experiment revealed that when a value of pH increases, a quantity of cobalt, which transforms into solid phase, increases (pH=5.0~8.0). Temperature dependence of rate […]
In contrast to real technology with the use of results obtained from laboratory studies, the combined technological circuit for manufacture simultaneously in one installation extractive a phosphoric acid both amorphous is developed on the basis of phosphorite and waste a sulfuric acid. The description of process carried out on the new technological circuit, technological regime […]
E-(k) diagrams of elektronik computer modeling with the use of Chebyshev coefficients to indicate energy of valence electrons of quasi-atoms containing chalcohalogenides of III-A group elements have been calculated, their physical-chemical properties identified.
Composition of some mineral waters of Azerbaijan to identify ions of Na+, K+, as well as heavy and carcinogenic metals has been analysed.
Chemical components of Scabiosa micrantha have been studied. Extracted and identified from overhead parts flavonoids – luteolin-7-O-β-D-glucozid (sinarozid), apigenin-7-O-β-D-glucozid(cosmosiin). Obtained fromthe sums ofroots saponins under acidic hydrolysis as aglycons is the oleanolic acid, and as sugars there have been detected D-glucose, L-arabinoseand L-ramnose.
Using methods of IR-, UV- and PMR-spectroscopy, the spectral characteristic of chemical structure of p-formylphenylacrylate and p-formylphenylmethacrylate has been examiner and it has been identified that they have advantagely S-cis conformation.
2,2′ -diamine-4,4′-bis(1,3-tiazole) (DABTA) forms new complexes of composition [M(DABTA)(CH3COO)2] with Zn(II) and Hg(II) acetate. Their IR, 1H and 13 C NMR spectras and termogravimetic properties have been investigated. X-ray stucture of the [Zn(DABTA)(CH3COO)2] shows the Zn(II) ion is coordinated by two nitrogen atoms of DABT and four oxygen atoms of two bidentate acetate anions. The […]
Modification of ethylene-propylen copolymer by benzilnaphtenat has been studied and main reological indices of obtained compositions at 130-150o C.
