Goal and objectives of the project

Development of adsorption-catalysis method to remove NH3, NO2, H2S, SO2 gases in aqueous environment by new generation composite materials. Fabrication of minimally absorbent materials (maximum hydrophobic surface) with high selectivity for the mentioned gases.

Main results
- Manufacturing modern composite materials on the basis of modified activated carbon, cationic zeolite and metal-organic coordination polymers.
- Research and evaluate the morphological and structural characteristics of the synthesized materials.
- Evaluation of the ability of materials to remove toxic gases in the aquatic environment.
- Development of a method to measure the concentration of gases in water.
- Development of a method to study the adsorption of gases.
Novelty and actuality and scientific meaningfulness of the results

- Development of a gas chromatographic method to measure the concentration of toxic gases in the aquatic environment
- Development of a method to study the adsorption capacity by gas pulse and static method in a hydrothermal vessel
