Agha, Muna Abd Ul Rasool Al-Kazragi, Ali H. Jawad, Lee D. Wilson, Hussein A. Kazem, Zeid A. ALOthman","doi":"10.1080/03067319.2025.2576558","DOIUrl":"https://doi.org/10.1080/03067319.2025.2576558","url":null,"abstract":"A new adsorbent was developed by integrating algae biomass (AG) into a chitosan (CN) matrix, followed by structural enhancement via crosslinking with pyromellitic dianhydride (PMDA) through a hydrothermal synthesis approach. This process resulted in the formation of a robust AG@CN-PMDA composite with improved physicochemical characteristics suitable for advanced adsorption applications. The AG@CN-PMDA composite was evaluated for its efficiency in removal of the cationic dye methyl violet 2B (MV 2B) from aqueous solution. The adsorption process was refined through the Box-Behnken design (RSM-BBD), evaluating three essential parameters: adsorbent dosage (A: 0.02–0.1 g/100 mL), pH (B: 4–10), and time (C: 5–20 min). The ideal conditions for attaining the best removal rate for MV 2B (86%) were determined based on the desirability function optimisation results, corresponding to 0.09 g/100 mL of AG@CN-PMDA, at a pH of 6.9 and time of 9.45 min. The adsorption isothermal analysis revealed a close fit between the experimental data of MV 2B adsorption and both the Temkin and Langmuir models, with the Temkin model showing a slightly better correlation. Furthermore, the adsorption kinetics are well-described by the pseudo-second-order model. The maximum adsorption capacity of AG@CN-PMDA was 162.3 mg/g at 25°C. The adsorption of MV 2B onto AG@CN-PMDA was spontaneous, endothermic, and entropy-driven as evidenced by negative Δ<i>G°</i> values. The binding of MV 2B dye onto the AG@CN-PMDA composite was facilitated through mechanisms such as hydrogen bonding, π–π stacking, and electrostatic attraction. These findings demonstrate that AG@CN-PMDA is an effective and sustainable adsorbent for the removal of cationic dyes from industrial effluents.","PeriodicalId":507993,"journal":{"name":"International Journal of Environmental Analytical Chemistry","volume":"1 1","pages":"1-23"},"PeriodicalIF":0.0,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147921978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid was fabricated by in situ growth of Ni nanoparticles on MOF-derived N-CNTs followed by hydrothermal sulfidation to form Ni<sub>x</sub>S<sub>y</sub>. This hierarchical nanostructure provided abundant active sites, large surface area, and enhanced conductivity. Electrochemical studies revealed outstanding nitrite sensing performance, with a wide linear range (0.2 μM–22 mM), high sensitivity (163.77 μA mM<sup>−1</sup> cm<sup>−2</sup>), and a low detection limit (0.2 μM). The sensor showed excellent selectivity, reproducibility, and stability. Real sample analyses, including water, beverages, and pickled brine, yielded recoveries of 98.71–103.87% with low RSDs. A smartphone-integrated portable sensing system was also demonstrated, enabling accurate on-site nitrite monitoring. This work offers an effective strategy for designing advanced, field-deployable electrochemical sensors for food safety and environmental analysis.","PeriodicalId":507993,"journal":{"name":"International Journal of Environmental Analytical Chemistry","volume":"1 1","pages":"1-18"},"PeriodicalIF":0.0,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147913828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
