This study evaluated the effectiveness of three carbon-based structures — graphene, printex, and biomass-derived biochar — for Cr<sup>6+</sup> adsorption in water, aiming to identify efficient and sustainable solutions for wastewater treatment. To investigate the influence of different carbon-based structures on Cr<sup>6+</sup> adsorption, the physical, chemical, morphological, and thermal properties, as well as particle sizes, were evaluated. Adsorption experiments were conducted under varying conditions of contact time, initial Cr<sup>6+</sup> concentration, and adsorbent dosage, with responses optimized through response surface methodology. Additionally, a Life Cycle Assessment (LCA) was conducted to evaluate the environmental impacts of the developed process, providing a broader sustainability perspective compared to conventional methods. Results indicated significant adsorption efficiencies for all materials: biochar achieved 85.1 % removal of Cr<sup>6+</sup> under optimal conditions (using a 100 mg dosage, at a concentration of 1 mmol.L<sup>−1</sup>, over 30 min of contact time); Printex reached 85.4 %, and graphene recorded the highest removal rate at 89 %. Adsorption isotherms were best described by the Langmuir model, with maximum capacities of 67.7 mg g⁻¹ for graphene, 30.4 mg·g⁻¹ for Printex, and 13.3 mg·g⁻¹ for biochar. The structural properties of each material influenced this difference in adsorption capacity. The layered structure of graphene and the rough morphology of printex contributed to its performance, while the porous morphology and surface functional groups of biochar also favored adsorption. Nevertheless, this study identifies biochar as a promising and cost-effective material derived from biomass waste, aligning with sustainability goals. The proposed LCA scenarios reinforce this advantage, demonstrating reduced environmental impacts — particularly in terms of human toxicity and aquatic ecotoxicity — and benefits from a circular economic perspective. Importantly, this work provides a direct and systematic comparison of three commonly used carbon-based materials under identical experimental conditions, thereby addressing a key gap in literature and guiding more effective selection of adsorbents for environmental applications.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"726 ","pages":"Article 137881"},"PeriodicalIF":5.4,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144738169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) methods were used to characterize the thermal behavior of THEDES.

The comparative analysis of the dissolution behavior of TAZ in solid and liquid forms in water at 37 <sup>о</sup>C was carried out. Dissolution of the obtained THEDES in water demonstrated a supersaturation phenomenon, characterized by a rapid increase in the content of the active pharmaceutical substance in the solution, and then a reducing of drug concentration to equilibrium values. The maximum concentration of the eutectic system of TAZ in an aqueous solution is 26.6 times higher than the aqueous solubility of the drug. Whereas, the thermodynamic solubility of the prepared liquid form of drug compared to the crystalline one, increases by 13.3 times.

Compared to partially aggregated pre-nucleation clusters (PAPNCs), PNCs exhibit a uniform distribution and larger dimensions, as confirmed by small angle X-ray scattering (SAXS) and dynamic light scattering (DLS) analyses, which reduce colloidal heterogeneity and bring the nanoparticle in precursor dispersion closer to the critical nucleation size. This promotes consistent nucleation, accelerates crystallization, and results in compact, pinhole-free films with enhanced crystallinity, reduced trap densities, and prolonged carrier lifetime.
