The aim - to study the kinetics of peroxide oxidation of typical organic toxicants in the presence of cation (Cu, Fe) - modified zeolite ZSM-5 by varying the process temperature, the ratio of reactants, the pH of the reaction medium, of catalysts. The influence of geometry catalyst and impact modifier on kinetic, external and internal diffusion reaction mode. Methods - spekro-dodetsylbenzolsulfonatu photometric determination of the concentration of sodium (DBS), elemental analysis with inductively coupled - plasma and mass spectrometer, micro-picture analysis. The main results - developed new methods for the synthesis of zeolites containing cations Fe (n+), by ion exchange and implementation of their outer surface layer of carbon by impregnation (aqueous solution of glucose, dextrin and methylcellulose) and their subsequent thermolysis. The influence of the carbon precursor in the formation of additional surface in the zeolite matrix. Established after the modification of zeolite surface area carbon composite materials increased by about 5%. And in the case of methyl cellulose, as a precursor of carbon, it is slightly more than in the case of glucose and dextrin. Modification of the surface of the zeolite carbon adsorption not increased the level of DBS and does not significantly affect the degree of degradation of DBS in long-term (3 - 5 days) oxidation. In the presence of carbon on the surface of the sample significantly accelerated schedule oxidant and there is a clear correlation between the rate of decomposition of hydrogen peroxide and the amount of carbon on the surface of the synthesized design. Created materials potentially be used as adsorbents and catalysts redox action. Scope - water treatment and water treatment.
