The study provides a comparative investigation into the adsorption capabilities of Hg using two MoS<sub>2</sub> (molybdenum disulfide) based nanocomposites: reduced graphene oxide/molybdenum disulfide (rGO/MoS<sub>2</sub>) and magnesium–aluminum layered double hydroxide/molybdenum disulfide (Mg-Al LDH/MoS<sub>2</sub>). Synthesis of the nanocomposites was achieved via a simple hydrothermal approach, followed by their characterization using X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, and Brunauer–Emmett–Teller surface area analysis methodologies. To determine the effectiveness of mercury adsorption, experiments were designed to examine the influence of several factors, including the amount of adsorbent, pH value, ionic strength, initial mercury ion concentration, and the duration of contact. The isotherm data were adjusted to the Langmuir, Freundlich and Temkin. The adsorption of Hg<sup>2+</sup> onto the rGO/MoS<sub>2</sub> and Mg-Al MgAl Mg-Al LDH/MoS<sub>2</sub> was consistent with the Langmuir model, indicating monolayer adsorption.

A polyethylene glycol-bridged Gemini surfactant was synthesized and evaluated for its interfacial and emulsifying properties, with particular emphasis on its ability to enhance the oil displacement efficiency of </span>NPs. FTIR and </span></span><sup>1</sup><span>H NMR characterization confirmed the successful synthesis of the novel Gemini surfactants (PEGnC). The results demonstrated an inverse correlation between critical micelle concentration (CMC) and spacer molecular weight, while interfacial activity was enhanced with increasing brine salinity. PEG6C (600 Da spacer) exhibited superior performance, achieving ultra-low interfacial tension (10</span><sup>−2</sup>-10<sup>−3</sup><span> mN/m) at 15–25 % NaCl concentrations while demonstrating optimal interfacial activity and emulsification capacity. The optimal PEG6C surfactant was subsequently combined with NPs to formulate a stable nanocomposite fluid, which maintained low viscosity and turbidity while achieving significantly reduced interfacial tension, indicating excellent dispersion stability and interfacial activity. The addition of PEG6C to NPs fluids could significantly improve the oil recovery efficiency of NPs fluids from 11.82 % to 30.66 %. This work establishes a promising strategy for combining Gemini surfactants with NPs to develop high-performance EOR systems.</span></div></div>","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"151 ","pages":"Pages 692-699"},"PeriodicalIF":5.9,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047971","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}
