Rezumat

The environment in the last 70 years has been intensely polluted as a result of a reckless human activity. The accelerated development of industry, the intense chemicalization of the agriculture, the increase in the number of inhabitants on the Earth planet and the living conditions of the population on the one hand and the elaboration, the slow implementation of environmental treatment technologies on the other hand, have contributed to the pollution of water, air and soil. The ecological chemistry has a special importance in the solving of environmental problems. The results of the studies of the processes and mechanisms of transformation, migration, catalytic decomposition, immobilization, adsorption etc. of organic and inorganic pollutants that enter the objects of the environment are at the basis for the development of high-performance technologies for environmental treatment. Synthetic and natural adsorbents have a wide application in water treatment, as well as in the detoxification processes of the human body. The paper presents the results of scientific research obtained in the Laboratory of Ecological Chemistry of the Institute of Chemistry in the field of synthesis, study of structural parameters and adsorption capacity of activated carbons obtained from renewable raw material from the Republic of Moldova by water vapor activation methods, in fluidized bed, microwave heating and chemical activation. The results of the research on the processes and mechanisms of sorption of heavy metal ions, organic pollutants on carbon adsorbents in the aquatic environment are also presented, which were the basis for the development of technologies for natural water purification and wastewater treatment. The scientific communication also presents the results of the chemical modification of the surface of pectins obtained from apple fruits by oxidation processes and the efficiency of removing lead and mercury ions from biological solutions from individual solutions and from mixtures of ions of these metals. The results of carbon enterosorbent tests in the process of elimination of exogenous metabolites and non-pathogenic bacteria from biological solutions are also presented.
