This type of wastewater typically contains fats, oils, and greases, along with petroleum-based substances like diesel oil, gasoline, and kerosene. OW is regarded as a severe threat to humans, plants, and animals in special and the environment generally, jeopardizing ecosystems. There is an increasing demand for efficient treatment techniques due to the increased OW worldwide discharge and stringent limits on effluent discharge. Traditional approaches have proven to be inefficient, costly, and time-consuming, often resulting in secondary pollution. The adsorption technique, on the other hand, is thought to be a more practical choice because of its ease of use, cheaper startup costs, and reduced need for land. With better separation efficiency and lower operating costs, the adsorption technique has become a viable option for treating OW. The development of super adsorbents with high adsorption capacities has further enhanced the effectiveness of this method. Advanced technologies in adsorption are constantly evolving to meet the current and future demands of OW treatment.","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"97 10","pages":"751 - 771"},"PeriodicalIF":0.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesis of this compound was confirmed by the Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR), elemental analysis (CHN), thermal analysis (TGA), and visible-ultraviolet (UV-Vis) spectroscopy. Moreover, the inhibitor corrosion properties of this compound in the acidic solution were analyzed through the electrochemical impedance spectroscopy (EIS), polarization, and quantum chemistry tests. According to the results, the sample containing NTO and SO(OH) had the highest rate of inhibition corrosion. Its efficiency was enhanced by increasing the concentration of inhibitors in the acidic solution, something which indicated the dominant role of the adsorption mechanism in improving the inhibitory properties of the system. Furthermore, the results of the polarization test depicted that the inhibitors acted as mixed inhibitors in an acidic medium and affected both anodic and cathodic reactions of corrosion through adsorption on the surface of the steel immersed in a corrosive medium.","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"97 9","pages":"708 - 723"},"PeriodicalIF":0.6,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143513209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TPA linked azomethine-based phenol were synthesized by the acid catalyzed reaction of aromatic/aliphatic amine and 4,4'-diformyl triphenylamine. Which were characterized by elemental, Fourier transform infrared (FT-IR) and 1H NMR spectral analysis. The thermosetting polymers were characterized via FT-IR spectral analysis. The incorporation of TPA moiety in connection with azomethine linkage improved the processability of the resulting polymers, therefore, synthesized polymers are soluble in a variety of common organic solvents. Thermal features of P1–P3 were evaluated via differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Aromatic TPA moiety in the thermosetting network has enhanced their thermal stability (upto 370°C) as compared to conventional epoxy : phenol thermosets. The photophysical properties of the thermosetting polymers were determined via UV-visible absorption and photoluminescence (PL) emission spectral analysis in NMP (10 μM) as well as in solid state. All the polymers were optically transparent and exhibit excellent blue light emission in the range 435–460 nm with PL quantum efficiency in the range 1.5–7.7. The mechanical stability of all the polymers was evaluated by tensile strength measurement. The above-mentioned characteristics indicate that the synthesized thermosetting polymers display appreciable thermal stability, efficient blue light emission and appreciable processability as well as good mechanical strength, which can be potential candidates as light emissive coatings and adhesives.","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"97 9","pages":"739 - 749"},"PeriodicalIF":0.6,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143513233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hereby, composites nTiO2/(1−n)CA-tc, where n – the mass ratio of TiO2 precursor and CA (n = 0.5, 0.7, 0.8, and 0.9); tc – the experimental calcination temperature (tc = 400, 500, 600, and 700°C), were synthesised by the solvothermal method. As a relevant result, the CA component was found to be in its amorphous form, while TiO2 existed in both anatase and rutile phases, which were finely dispersed on the composite surface. The unit cell volume (Vc) of the anatase structure and its average crystallite size (D) varied depending on tc and n, and so did the corresponding samples’ photocatalytic performance. It was discovered that the sample 0.5TiO2/0.5CA-400 showed the highest HCHO conversion (xHCHO) compared to the other synthesised ones, with xHCHO ≈97% after a conversion time of 75 min. The enhanced activity of 0.5TiO2/0.5CA-400 was due to its higher Vc (~137.2520 nm3) and lower D (~6.7 nm), which was predicted to have a higher specific surface area. Thus, this study has confirmed the effectiveness of developing TiO2 photocatalysts based on the CA substrate for HCHO oxidation and exhibited the potential to extend the application to other volatile organic compounds (VOCs).","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"97 8","pages":"686 - 694"},"PeriodicalIF":0.6,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The products were characterised by IR, XRD, TGA, and UV spectroscopy, which showed that the structures were correct and that the catalysts were thermally stable. The synthesis of BISBC by IL-Fe-catalysed ISB was carried out and the structural characterisation and synthetic conditions of BISBC were optimised by orthogonal tests. The experimental results showed that four factors, i.e. feeding ratio, catalyst dosage, reaction temperature, and reaction time, affected the yield of the BISBC prepolymer in descending order. The optimum process conditions for the BISBC yield were defined: feeding ratio n(DMC) : n(ISB) = 5; catalyst dosage = 1.0 wt %; reaction temperature = 80°C; reaction time = 5 h. Under these reaction conditions, one-way experiments were again carried out for validation, and the BISBC yield was as high as 75.32%.","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"97 8","pages":"677 - 685"},"PeriodicalIF":0.6,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
