PERSPECTIVE MODIFIERS FOR ANIONEXCHANGE MEMBRANES BASED ON POLYMERS WITH QUATERNARY NITROGEN ATOMS, WHICH INCLUDED IN FIVE- AND SIX-MEMBERED HETEROCYCLIC RINGS

abstract 1231609085 issue 123 pp. 1256 – 1267 30.11.2016 ru 248
The present work describes the chemical synthesis of poly-N,N-diallyl pyrrolidinium bromide and polyN,N-diallyl morpholinium bromide - high-molecular compounds containing quaternary nitrogen atoms, which included in two five- and/or six-membered heterocyclic rings. These polymers are perspective modifiers for industrially produced anion-exchange membranes, the use of which should significantly improve the resistance to degradation of the membranes at over-limiting current regimes. The structure of obtained polymers was characterized by FTIR, 1H and 13C NMR spectroscopy. The optimal reaction conditions, which increase the yield of desired products, were defined. It is shown that is preferable to use 1-butanol as a solvent and benzoyl peroxide as an initiator

THE SPECIES COMPOSITION, BIOMASS, QUANTITY OF THE COASTAL ZOOBENTHOS AND FISH CAPACITY IN SOME OF KARASUN LAKES

abstract 1301706054 issue 130 pp. 774 – 788 30.06.2017 ru 20
We have presented information about species diversity of the coastal zoobenthos in some of Karasun lakes, Krasnodar. We have shown methodology information and reported the research area. We have made a taxonomic analysis. The biomass and the quantity of the main zoobenthos groups were calculated. Based on the two main fodder objects - Olygochaeta and Chironomidae and the P/B coefficient, there was calculated zoobenthos production of the studied lakes. The potential fish capacity was defined
