Nowadays, ultraviolet (UV) irradiation heterogeneous Fenton-like reactions have widespread used in organic wastewater treatment. In this paper, Fe2+ and Cu2+ were load in Na-Y molecular sieve using impregnation method. Fe-Y, Cu-Y and Fe-Cu-Y catalysts were obtained. The Fe-Cu-Y catalyst showed good performance in the degradation of 6-nitryl wastewater. When the volume of 6-nitryl wastewater is 100 mL, the optimal reaction conditions were found to be 3mL of hydrogen peroxide, 7.5g of catalyst weight, 250W of UV power. Under these conditions, the degradation rate of CODCr can be up to 97.0%.


The authors' methodic for assessing the role of chemical and physic-chemical factors during the structure formation of gypsum stone is presented in the article. The methodic is also makes it possible to reveal the synergistic effect and to determine the ranges of variation of controls factors that ensure maximum values of such effect. The effect of a micro-sized modifier based on zinc hydro-silicates on the structure formation of building gypsum is analyzed and corresponding dependencies are found. It is shown that effects of influence of modifier on the properties of gypsum compositions are determined by chemical properties of modifier. Among the mentioned properties are sorption characteristics (which depend on the amount of silicic acid and its state) and physicochemical properties - the ability to act as a substrate during crystal formation. The proposed method can also be extended to other binding substances and materials. This article contributes to the understanding of the processes that occur during the structure formation of composites, which will make it possible to control the structure formation in the future, obtaining materials with a given set of properties.
