For example, cadmium electroplated coatings require corrosion resistance, since they are operated in tropical climates, in underground tunnels. Zinc coatings are widely used in building structures and roofing, on electrified railways and high-voltage power lines, in the mining industry and water pipes, as well as for galvanizing the body material in modern all-terrain vehicles to pass in hard-to-reach places without being subjected to corrosion. The object of our research is the process of electrodeposition of cadmium and zinc from simple acidic electrolytes with surfactants, which are thiourea derivatives of dialkyl-phosphorous acids in the current density range of 0.5-3.5 A /dm2, at room temperature.

It is shown that the inoculation of humic acids on inorganic carriers is more successful with the preliminary activation of the surface of burnt rocks. The acidic and sorption properties of grafted surfaces of humic sorbents with respect to heavy metal ions have been studied. It is shown that many of the modifying additives on the surface of the inorganic carrier can increase these properties by 1.2-2.0 times in comparison with the original rock. Surface modification was carried out by means of impregnation with water solutions of the modifier and subsequent heat treatment; heating at boiling point in water solutions with subsequent heat treatment of precipitation. The interaction of modifiers with the surface occurs by the type of ion exchange for silanol or aluminol groups with weak acidity. It is also possible to connect via hydrogen bonds or dipole-dipole and induction interactions. It was found that the degree of grafting of humic compounds is significantly higher on the activated surfaces of the burnt rock. The content of the modifier on the surface of the carrier is 10-40%, depending on the experimental conditions and the nature of the modifier. The most active modifiers are sodium phosphate and potassium carbonate. The kinetics of the interaction of the surface of the burnt rock with potassium carbonate of different concentrations to reduce the specific electrical conductivity of the reaction mixture over time is studied. A comparative study of the sorption properties of grafted surfaces was carried out, depending on the nature of the functional groups of the humic component of the sorbent, the nature and concentration of the metal ion. The degree of sorption of metal ions with mineral carriers increases from 12-15% to 20-90%, depending on various factors. The highest sorbability of new huminomineral sorbents was noted for lead ions.","PeriodicalId":43167,"journal":{"name":"News of the National Academy of Sciences of the Republic of Kazakhstan-Series Chemistry and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48055303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Scientists all over the world are looking for various raw materials and methods to use the vast resources of natural gas as a substitute for petrochemicals. In this regard, great attention is drawn to natural gas as an alternative source of raw materials for petrochemical industries. The purpose of this work is to study the reaction of methane dehydrogenation on new 20%La-10%Ce20%Mg-50% glycine catalysts prepared by the SHS method to identify the optimal conditions for their preparation, concentration and ratio of metals, the influence of contact time and process temperature on the direction and mechanism of the reaction. The results of the study of 20% La-10% Ce-20% Mg-50% glycine catalyst prepared by the SHS method in the process of oxidative dehydrogenation of methane into C2 hydrocarbons are presented. On the basis of experimental studies, it was found that the composition of the catalyst exhibits high activity in the above reaction under the found optimal conditions. Thus, the influence of reaction temperature on the developed composition of catalysts for oxidative conversion of methane has been determined that the optimum temperature for the selective formation of ethane and ethylene is T=700o С. It was found that for selective oxidation of a mixture of CH4: O2 : Ar in C2 hydrocarbons the optimal conditions are: T=700o С, CH4:O2=2,5:1, 5000 h-1.","PeriodicalId":43167,"journal":{"name":"News of the National Academy of Sciences of the Republic of Kazakhstan-Series Chemistry and Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46916640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
