RESEARCH OBJECTIVES

 1.  Ultrafiltration membranes

      •  Systematic research literature review on acrylic ultrafiltration membranes and on the recommended comonomers for the hydrophilicity augmentation, for the molecular imprinting and for the covalent immobilization of enzymes.
      •  Copolymerization studies for development of process parameters for optimal production of the target copolymer. Rheological studies for the preparation of the membrane casting solutions containing the template hormone for the molecular imprinting.
      •  Phase inversion studies devoted to the obtaining of the ultrafiltration membranes and extraction studies for obtaining molecularly imprinted membranes.
      •  Studies on the polymer analogue reaction for the activation of the membrane for the enzyme immobilization. Enzyme covalent immobilization on the activated molecularly imprinted membrane.
      •  Physical, chemical and structural characterization of the raw materials, intermediate products and membranes. Hydrodynamic characterization of the membrane, cut off, selectivity of the imprinted membrane and bioactivity of the modified membrane.

 2.  Nanoporous carbon

      •  Analysis of the composition of the initial materials using chemical and physico-chemical methods of analysis. Selecting of the composition of the starting mixture and appropriate conditions of thermo-catalytic treatment for obtaining monolithic carbon-selecting of catalyst and temperature of treatment. Selection of optimal conditions of carbonization of the monolithic carbon. Study on the influences of the composition of the precursor, the type of thermo-catalytic treatment, rate of rising the temperature and final temperature of carbonization, on the porous structure and surface of the carbonized material.
      •  Determination of optimal conditions of activation of carbonized material permitting formation of developed pore structure and high surface area.
      •  Comparison of the data from physical and chemical activation and assessment of the advantages and disadvantages of both methods. Valuation of the possibilities to adjust the properties of the obtained nanoporous carbon according to their purpose, varying the composition of initial mixture and condition of treatment.
      •  Creation of novel process for obtaining different nanoporous carbons on the base of various precursors (low rank coals, agricultural by-products, products from biomass, polymers and coal treatment processes). Comparison of the properties of obtained carbons with those of commercial samples used for the same purposes.

 3.  Natural zeolites

      •  Investigation of physico-chemical properties of natural zeolites from different deposits using modern methods of analysis. Selection of the most appropriate zeolites for further investigations on the base of their mechanical and physico-chemical characteristics.
      •  Determination of the adsorption capacity in static and dynamic conditions of the selected zeolites for the main inorganic and organic pollutants in exhaust waters.
      •  Studying the possibilities to increase the adsorption capacity of the zeolites by thermo-chemical treatment.
      •  Developing new methods for regeneration of exhausted zeolites and determining the possibilities for their multifold use.
