Zero valent aluminum and zero valent nickel metals have been used by numerous researchers both domestically and internationally to removal U(VI) from aqueous solution due to their unique chemical properties. In this work, Al0/Ni0 bimetallic material (Al0/Ni0-BM) was prepared by synchronous liquid-phase reduction method. Due to the structure of bimetallic material and synergistic effect, it exhibited a higher removal rate compared with single zero valent metal. At room temperature (25 ℃), the initial concentration of U(VI) was 20 mg/L, pH was 3.0, dosage was 0.25 g/L, and the removal rate could reach 98.90% after 60 min of reaction, well-fitting with the pseudo-second-order kinetic model, reduction model, and Langmuir isothermal adsorption model. The high removal performance was attributed to the electron transfer mechanism between material and U element and the adsorption effect of corresponding hydroxides. The thermodynamic parameters demonstrated that the adsorption of U(VI) on the Al0/Ni0-BM was an endothermic and spontaneous process controlled by physical and chemical adsorptions. And the synthesized Al0/Ni0-BM effectively improved the aggregation of zero valent metals in monomers. In conclusion, Al0/Ni0-BM showed an excellent potential for U(VI) removal from aqueous solution by zero valent bimetallic materials.</div>","PeriodicalId":753,"journal":{"name":"Research on Chemical Intermediates","volume":"50 9","pages":"4485 - 4501"},"PeriodicalIF":2.8,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141742666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For these reasons, the synthesis of benzothiazoles is very important in organic synthesis. In this synthetic approach, we found that the utilization of Fe3O4@DOP-Amide/Imid-CuCl2 nanocomposite in the presence of KOAc in ChCl-Urea as solvent is an eco-friendly and efficient catalytic system for the synthesis of 2-aryl benzothiazoles through one-pot three-component reactions of 2-iodoaniline and aromatic aldehydes with thiourea as sulfur source. Under this catalytic system, a broad spectrum of 2-aryl benzothiazoles were successfully synthesized with high to excellent yields. Compared to the reported catalysts or magnetic nanocatalysts, the Fe3O4@DOP-Amide/Imid-CuCl2 nanocatalyst has the following series of features: design of a magnetic ligand through ammonolysis reaction, high magnetic property of the Fe3O4@DOP-Amide/Imid-CuCl2 nanocatalyst, high catalytic activity in the synthesis of benzothiazole derivatives, reusability and high stability of the synthesized magnetic catalyst. The SEM, VSM, BET, and ICP-OES techniques revealed that the recovered Fe3O4@DOP-Amide/Imid-CuCl2 catalyst (after 8 times) had high stability because the magnetic nature, structure, and surface of the recovered catalyst was similar to the fresh catalyst.<h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":753,"journal":{"name":"Research on Chemical Intermediates","volume":"50 9","pages":"4275 - 4300"},"PeriodicalIF":2.8,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141742667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulted polymers N/S bi-heteroatom functionalized polymer HCP-CT and N/O bi-heteroatom functionalized polymer HCP-CF both have good adsorption property for organic dyes such as methyl orange (MO) and methylene blue (MB) in aqueous solution due to its rich pore structure, high specific surface area and rich-heteroatoms of pore surface. It is worth mentioned that the maximum adsorption capacity (qmax) of cationic dye MB by the porous polymer HCP-CT at room temperature was reached up to 1571.46 mg/g, which is much higher than that of most reported porous materials. Furthermore, the adsorption capacity of HCP-CT for the cationic dye MB was more than seven times that of the anionic dye MO (qmax = 212.77 mg/g). Also, the polymer HCP-CF for the MB adsorption capacity (qmax = 352.11 mg/g) was more than twice higher than that of anionic dye MO (qmax = 131.75 mg/g). The above trends may be because of the stronger electrostatic interaction between the negatively charged N-S/O bi-heteroatom of HCP-CT and HCP-CF with the cationic dye MB than that of MO. In addition, the removal percentage of polymers HCP-CT and HCP-CF still remained above 80% after five adsorption–desorption cycles.
