MCPs were synthesized and characterized using Raman spectroscopy and scanning electron microscopy (SEM) to assess their structural modifications post-mercerization. Adsorption assays were conducted under various experimental conditions, including agitation rate, pH, temperature, effluent concentration, and MCP concentration. The adsorption capacity was modeled using Langmuir, Freundlich, Dubinin-Radushkevich, and Temkin isotherms, with Langmuir providing a better fit (R<sup>2</sup> = 0.9884), indicating indicating a monolayer adsorption of Cr ions onto the MCPs surface. Results showed a maximum adsorption capacity of 28.17 mg/g for Cr, with optimal conditions identified as 400 rpm agitation, pH 5.0, 35 °C temperature, and 25 mg/L MCP concentration. Multiple regression analysis highlighted pH and effluent dilution as significant factors affecting adsorption efficiency. Additionally, cluster analysis and Detrended Correspondence Analysis (DCA) confirmed the complex interactions among the variables. Our findings suggest that mercerized MCPs are a promising and sustainable solution for Cr removal from tannery effluents, offering a high adsorption capacity and potential for environmental application.

Phumdi, a unique biomass from the Loktak Lake ecosystem, serves as a sustainable and cost-effective precursor for activated carbon production due to its rich organic composition and functional groups. Large accumulations of Phumdi are commonly found along the periphery of Loktak Lake, where they are often regarded as waste. To account for variations in biomass properties, samples were collected from three different sites: a national park, an agricultural area, and a residential area. BET surface area analysis confirmed the porous nature of the activated carbons, with values ranging from 2.722 to 5.940 m<sup>2</sup>/g across different biomass sources. FTIR characterization identified key functional groups, including hydroxyl, alkyl, and carbon–carbon bonds, which play a crucial role in Fe (II) adsorption. Amongst the batch analysis parameters, the agitation speed was found to be optimum at 250 rpm, and the temperature at 298 K, with an equilibrium time of 120 min. Kinetic studies followed a pseudo-second-order model, indicating chemisorption, while isotherm analysis confirmed Langmuir model conformity, with a maximum adsorption capacity ranging from 1.12 to 6.50 mg/g. Thermodynamic studies confirmed that the adsorption process is exothermic and spontaneous, driven by energy release and a decrease in free energy. Fixed-bed experiments using activated carbon from phumdi biomass from an agricultural area were conducted at varying flow rates (2 mL/min and 4 mL/min), bed depths (20 cm, 40 cm, and 60 cm), and influent concentrations. The maximum throughput of 12 L was achieved before significant breakthrough at 5 mg/L, 4 mL/min, and 60 cm, indicating optimal adsorption performance under these conditions.

In this work, the removal of diesel fuel (DF) from DF-spiked soil was studied for 138 days in six microcosm experiments, with different initial Carbon-to-Nitrogen ratios (C/N) (120, 180), and moisture content (MC) between 8 and 15% (<i>w/w</i>). A hybrid model predicting DF removal dynamics was proposed, where the instantaneous removal rate was modeled as an artificial neural network (ANN) function of initial C/N, MC, DF concentration, and time. DF removal rate was estimated from 250 interpolated (Akima method) points (in each experimental set) used to train the ANN model. A double-hidden layer (4–10–7–1) architecture offered the best fitness on the test subset (<i>R</i><sup>2</sup><sub>test</sub>: 0.996), as well as on the entire dataset (<i>R</i><sup>2</sup>: 0.995). LIME and SHAP analysis suggested the significance of DF concentration and MC on the ANN model explanation. Numerical integration of ANN embedded rate expression for DF removal reveals an excellent fit (<i>R</i><sup>2</sup> &gt; 0.99) to microcosm dynamics. The modeling strategy adopted in this study can be replicated in other complex bioprocess systems with limited data availability.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 5","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
