We here report the valorization of chitosan-derived humins for removal of heavy metal ions to enhance the atomic economy of the biomass conversion. Chitosan-derived humins were synthesized by catalysis of oxalic acid (OA), whereby the adsorption performance for Cd(II), Cr(III) and Cr(VI) was explored. The adsorption data were well fitted by the pseudo-second-order kinetic model, complemented by the Freundlich and Temkin isotherm models, revealing maximum adsorption capacities of humins for heavy metal ions as follows: 358.7 mg/g for Cr(VI), 152.6 mg/g for Cd(II), and 40.2 mg/g for Cr(III). The mechanistic studies revealed that the adsorption of Cd(II) and Cr(III) by humins mainly occurs through ion exchange (carboxyl groups) and surface complexation (hydroxyl, carbonyl, and amino groups). In comparison, the adsorption of Cr(VI) by humins involves electrostatic attraction, alongside ion exchange and surface complexation. After carbonization and activation, the specific surface area increased markedly, however the adsorption capacity decreased owing to reduced oxygen- and nitrogen-containing functional groups. Competitive adsorption studies, industrial wastewater experiments, and cyclic adsorption tests demonstrate that humins exhibit remarkable adsorption performance even in complex environments. This work highlights that chitosan-derived humins are promising adsorbents for the remediation of heavy metal ions.</div></div>","PeriodicalId":9749,"journal":{"name":"Chemical Engineering Journal Advances","volume":"24 ","pages":"Article 100894"},"PeriodicalIF":7.1,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145216844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Na-ETS-4 was ion-exchanged with Ba ²⁺ to form microporous Ba-ETS-4, and characterized using XRD, SEM and EDX spectroscopy. Adsorption isotherms and fractional uptakes were recorded at three different temperatures of 30, 50, and 70°C to evaluate the effect of temperature on adsorption capacity and kinetics. Time-dependent fractional uptake recorded at different temperatures confirmed that ethene diffuses significantly faster than ethane in Ba-ETS-4, which can be attributed to ethene’s smaller molecular size, i.e. at 30°C, the time-constant diffusivity of ethene was 4.75 times higher than ethane. Though diffusivity increases for both gases with temperature, ethane rises more, reducing the ethene/ethane diffusivity ratio from 3.58 to 3.09 between 50 °C and 70 °C. Moreover, a high ethene/ethane kinetic selectivity of 12.5 was observed at 30 °C. Breakthrough experiments further highlighted the impact of diffusion limitations on separation. A comprehensive analysis has been performed for ethene/ethane mixtures between 30 and 90°C, ethene/ethane compositions varying from 10/90 (vol/vol%) - 90/10 (vol/vol%) and different regeneration conditions. Ethane exhibited a sharp breakthrough front, as it was excluded from adsorption in mixture conditions. A broader profile was observed for ethene, which its adsorption is affected by diffusion limitations. At higher temperatures, ethene’s breakthrough became sharper and more delayed, indicating reduced diffusion limitations. Optimal separation was achieved at 70 °C based on ethene uptake and breakthrough time difference. Given the strong adsorption in Ba-ETS-4, a TSA process is required for complete desorption of the adsorbed hydrocarbons.</div></div>","PeriodicalId":9749,"journal":{"name":"Chemical Engineering Journal Advances","volume":"24 ","pages":"Article 100890"},"PeriodicalIF":7.1,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145216842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that both CDP and CS-18 cells perform well under 10 mA/cm² and 0.38 atm of partial pressure of water vapor (p(H₂O), while under lower p(H₂O)=0.20 atm, only CS-18 cells can stably operate. Under higher 25 mA/cm² and p(H₂O)=0.20 atm, CS-18 cell also fails to retain its original performance, exhibiting degradation.

Using response surface methodology (RSM) with a full factorial design (FFD) of experiments, the effects of temperature (160-240°C), reaction time (1-24 h) and particle size (50-1000 µm) on furanic compound production were evaluated. Statistical analysis revealed that temperature was the most influential factor, followed by reaction time, while particle size had no significant effect, despite differences in composition: small sizes are richer in cellulose and lignin, and large sizes are richer in hemicelluloses and extractives. Kinetic modeling confirmed that 5-HMF, F, and 5-MF act as intermediates in the transformation of PB-derived sugars to humins. The pH profile during HTC correlated with furanic compound evolution, initially decreasing due to acid formation, then increasing as less acidic byproducts, likely phenolics, formed.
