Therefore, their processing in order to obtain valuable products is an urgent task. As a result of the reduction electric smelting of phosphorite raw materials in the Novo-Dzhambul phosphorus plant, about 150-160 kg of cuttrel dust is formed per 1 ton of yellow phosphorus. The resulting cuttrel dust is considered as a secondary raw material, it can be used to obtain phosphoruscontaining mineral fertilizers, since the boiler dust contains a proportion of phosphorus and other useful components. The purpose of this work is the processing of phosphorus production waste - cuttrel dust with the use of sulfuric acid to obtain phosphorus-containing mineral fertilizers. Methodology. For the processing of cuttrel dust under experimental conditions, instrumental test methods were chosen using a scanning electron microscope (SEM) of the Jeol JSM-6490l V brand, a multi-parameter portable cyberscanner (PCD 650 Eutech) and a Q-1500 Derivatograph. Results. According to the results of microscopic studies, it was determined that the content of the main useful component in the cuttrel dust P2O5 in the range of 30-31%. The thermodynamic regularities of the process of decomposition of cuttrel dust with the help of a solution of sulfuric acid have been studied. The standard thermal effects of changes in the enthalpy, entropy and the value of the Gibbs energy of the system at a temperature of 333–363K were determined using the HSC-6 complex program. The methods of mathematical processing are considered in order to determine the reliability of the results of the experimental work. The optimal technological parameters of this process have been established and determined. Conclusion. A technology has been developed for obtaining phosphorus-containing monocalcium phosphate based cuttrel dust from the waste of the Novo-Dzhambul phosphorus plant using sulfuric acid solutions. The advantage of the resulting phosphorus-containing component is that it has a high solubility and absorption of phosphorus to plants. They are also characterized by a high content of phosphorus-containing substances, which ensure the growth and productivity of agricultural plants and plant resistance to environmental stress factors.","PeriodicalId":9856,"journal":{"name":"Chemical Journal of Kazakhstan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74192832","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}

Many methods of bitumen modification include the oxidation of a heavy oil residue to obtain the target product and its further compounding with the finished bitumen. Old oil sludge from oil sludge storage tanks has been used as the oil residue. Oil sludge is prepared by dehydration, the water content should not exceed no more than 5 wt. % and separation of mechanical impurities up to a content of not more than 16.4 wt. %. Purpose of the work. The main objective of the study is to develop a technology for modifying oil bitumen with industrial waste for the disposal of oil sludge, and to show the possibility of improving the physical-chemical, rheological characteristics of modified bitumen. Results. In the process of bitumen modification, the physical-chemical characteristics of the modified bitumen have been studied. It has been established that the composition of oil sludge from the Uzen and Zhetybai oilfield of the Mangistau region contains a significant amount of heavy oil residues and a small amount of mechanical impurities. From the conducted laboratory esearch, it has been found that oil sludge can be used as a filler in the modification of bitumen. Conclusion. Used oil sludge can be used as a bituminous base modifier without removing the mechanical impurities. Polymer-bitumen compositions have been prepared and the optimal parameters for the process of preparing polymer-bitumen binders have been determined.","PeriodicalId":9856,"journal":{"name":"Chemical Journal of Kazakhstan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87671751","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}

Nutrients losses also occur because of natural processes (erosion, leaching, etc.). It is necessary to replenish the missing nutrients with the use of humate-containing organomineral fertilizers to preserve soil fertility and increase productivity. The purpose of this work is to study the processes of iron (III) phosphates interaction with potassium humate and to obtain humate-containing organomineral fertilizers. Methodology. Chemical analysis, infrared spectroscopy, X-ray phase analysis methods have been used. Results and discussion. The processes of obtaining humate-containing organomineral fertilizers by the interaction in the systems “iron dihydrogen phosphate - potassium humate”, “iron hydrogen phosphate - potassium humate” and “iron orthophosphate - potassium humate” have been studied. It has been determined that an increase in the S:L ratio from 1:3 to 1:6 leads to an increase in the content of the digestible forms of Р2О5 up to 44.70%, nitrogen up to 1.85% and the output of humic substances up to 79.23%. An analysis of the IRS data indicates the multicomponentness and complexity of the composition of humate-containing organomineral fertilizers samples. Conclusion. It has been shown that the absorption bands of humic compounds of various functional groups and various substitutions phosphates are superimposed, while the shape of the absorption bands distorted, and their maxima have shifted to the high- or low-frequency area. It has been found that, regardless the phosphate ionnature, an increase in the ratio of S:L leads to a decrease in the absolute content of total, water-soluble and assimilable forms of P2O5. Concurrently, the phosphate part almost completely converted into the assimilated form. It has been defined that adding of the potassium humate, makes all phosphorus, which is in the indigestible form in the iron phosphates, almost completely pass into a mobile and assimilable form. It has been revealed that the addition of potassium humate into the systems with iron phosphates of various degrees of substitution makes it possible to neutralize the residual acidity of the pulp, and the neutralization process proceeds without P2O5 retrogradation. The resulting products have good physical, mechanical and fertilizer properties.","PeriodicalId":9856,"journal":{"name":"Chemical Journal of Kazakhstan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86207981","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}

Cadmium plating is flexible, easily amenable to rolling, stamping, bending. Freshly prepared sheathing is better welded on acid-free fluxes than zinc. Goals and objectives. A study of the technology of cadmium tape, made of stainless steel, grade 2X18Н10T. A comparative analysis of the types and composition of cadmium electrolytes has been carried out. The factors affecting the quality of the resulting packaging are investigated, the calculation of the observed main indicators of products after electrolysis has been carried out. Results. Before coating the surface of metal products, geometric calculations of the surface of the coated products have been carried out, and their results have been processed to correctly select the density and current strength for a given operating mode. It has been established that the quality of the coating undergoes changes depending on the composition of the electrolyte, its temperature and current density. The surfactant has contributed to the production of a durable packaging layer with the possibility of increasing potency during use, including the work with such surfactants as dextrin, gelatin, carpentry glue. Conclusion. It has been shown that the cadmiumcoated tape has no gloss unless a surfactant is used.
