Addressing this issue, this study focuses on the synthesis and optimization of superparamagnetic chitosan-coated magnetic composites (Cs–Fe<sub>3</sub>O<sub>4</sub>) as an efficient adsorbent for 4-NP removal from water. Among the tested formulations, the 1:2 Cs–Fe<sub>3</sub>O<sub>4</sub> composite exhibited superior magnetic properties, larger surface area, and higher adsorption capacity compared to the 1:1 ratio, resulting in enhanced removal efficiency. Its superparamagnetic behavior enables easy separation and reusability, maintaining over 80% efficiency after five adsorption–desorption cycles. The Taguchi method identified optimal removal conditions─pH 8, a 10 min contact time, and a dosage of 0.5 mg/mL─achieving nearly 100% removal efficiency. Kinetic analysis revealed that the adsorption process followed pseudo-second-order behavior, while isotherm studies confirmed Langmuir monolayer adsorption with a maximum capacity (<i>q</i><sub>max</sub>) of 168.28 mg/g. Thermodynamic analysis demonstrated the exothermic and spontaneous nature of the process, making Cs–Fe<sub>3</sub>O<sub>4</sub> a highly effective and sustainable solution for wastewater treatment.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"19 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on the design and synthesis of a series of novel biobased thermosetting polymers using isosorbide, furfuryl amine, and two structurally distinct bismaleimide cross-linkers based on reversible Diels–Alder (DA) reactions. Nuclear magnetic resonance (<sup>1</sup>H NMR) and Fourier transform infrared spectroscopy (FTIR) were employed to confirm the successful preparation of isosorbide/furfuryl amine linear prepolymer (ISFA-OH) and isosorbide/furfuryl amine DA cross-linked polymer (ISFA-DA). The mechanical and thermal properties of ISFA-DA could be effectively and rapidly tuned by adjusting the structure and content of the maleimide cross-linkers, achieving tensile strengths ranging from 8.2 to 79.8 MPa, elongations at break from 6.5 to 100%, and glass transition temperatures (<i>T</i><sub>g</sub>) between 26 and 93 °C. Differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) results confirmed the presence of thermal reversible DA and retro-DA reactions within the ISFA-DA cross-linked polymers. The thermal reversible DA reaction endows the ISFA-DA cross-linked polymer with recyclability. We investigated the mechanical properties before and after recycling through both thermal solution and thermomechanical recycling methods, finding that the ISFA-DA cross-linked polymer retains over 90% of its original mechanical strength after thermal solution and thermomechanical recycling. This work provides a novel and promising strategy for design and preparation of a series of high-performance-biobased thermosetting materials with adjustable thermomechanical properties and excellent recyclability.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"2 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OAE is a process by which the surface of the oceans is realkalinized to promote CO<sub>2</sub> absorption from air by converting CO<sub>2</sub> to carbonates for long-term storage in the oceans. The capacity of the BMED stack was designed to process ∼139 000 m<sup>3</sup>/year of desalination brine, resulting in 47 200 t/year of 2.1 wt % NaOH solution. The OAE plant was modeled using colocation with a desalination plant in southern California. Three scenarios were investigated, each focused on a different valorization of the BMED process byproduct of 46 600 t/year of 1.8 wt % HCl solution: selling (1) dilute HCl without further processing, (2) dilute HCl distilled to 20 wt % using carbon-free (solar) energy, and (3) dilute HCl distilled to 20 wt % using waste heat from a nearby power plant. The levelized cost of CO<sub>2</sub> sequestration from the OAE plant, assuming no return on investment, ranged from 848 to 1076 USD/t of CO<sub>2</sub>, depending on the scenario. Subsequently, a discounted cash flow analysis was conducted to assess the price at which carbon credits would have to be sold as revenue source to make a profit on the plant. Our analysis indicates that the cost of energy, labor, loan repayment, and membrane replacement, as well as the inefficiency of commercial membranes, drive the economics of BMED for OAE, while highlighting the necessity to generate alternative byproducts other than HCl. Nevertheless, these high costs (1395–2315 USD/t of CO<sub>2</sub>) align with carbon credit prices currently indicated in contracts signed within the voluntary carbon market. A reliable outlook indicates that technical improvements and better economic perspectives can reduce the levelized cost of CO<sub>2</sub> down to 394 USD/t of CO<sub>2</sub>.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"56 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143653968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
