In this manner, a dual-action novel formulation has been assembled that presents a modified chitosan-Schiff base biopolymer by magnetite and zinc oxide nanoparticles as active centers for selective malachite green adsorption and preventing the growth of microorganisms in the medium. The presented novel porous composite material is characterized by the presence of two cost-effective and efficient surface modifiers (magnetite, zinc oxide nanoparticles) which enhanced the adsorption process rather than the presence of one as reported in the recently reported studies. The dual action of the presented compound as microorganisms' defeater and malachite green adsorbent comprises its novelty among the recently presented compounds. Herin, a novel chitosan-Schiff base (CS-SB) was synthesized by the reaction of Chitosan and (E)-3-(4-hydroxy-3-methoxyphenyl) acryl aldehyde. The prepared Schiff base was modified by magnetite using the co-precipitation method. The magnetic chitosan was impregnated with zinc oxide (ZnO) in the form of nanoparticles to produce Schiff base/ZnO nanocomposite (Mag-CS-SB/ZnO). The prepared compounds were characterized using infrared spectroscopy, X-ray diffraction, Brunauer–Emmett–Teller, zeta potential analyses, and thermal gravimetric analysis, and tested in remediation of MG from aqueous medium. The adsorption parameters: dye concentration (25–100 mg/L), biosorbent dosages (5–60 mg), pH (2–9), and time (10–360 min) were studied. The Maximum adsorption capacity was 34 mg/g after two hours at ambient temperatures. Antibacterial activity of the prepared compounds was scanned for Gram-positive (<i>Bacillus cereus and Staphylococcus aureus</i>) and Gram-negative (<i>Escherichia coli and Pseudomonas aeruginosa</i>) bacteria. The inhibition efficiency was ordered as Mag-CS-SB/ZnO nanocomposite ˃ CS-SB ˃ Chitosan. Mag-CS-SB/ZnO nanocomposite displayed outstanding antibacterial activity as comparable with commercial antibiotics (Streptomycin). The bonding between MG and biosorbent was shown to be predominantly caused by chelation and electrostatic adsorption, as proved by the density functional theory. Throughout five cycles, the biosorbent was effectively regenerated and maintained over 90% of its adsorption capacity, suggesting that it could find a beneficial and promising multi-functional adsorption compound for practical application in water treatment.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"21 16","pages":"9955 - 9976"},"PeriodicalIF":3.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257892","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}

In this paper, we report a direct bubbling and a two-step acidification process for lignin isolation from black liquor of the pilot scale bioethanol production and its utilization as lead adsorber. This research investigated how Pb (II) ions adsorbed onto new modified lignin recovered from black liquor called dimethylamine-soda lignin. Alkaline pretreatment at 150 °C and 5 kg/cm<sup>3</sup> by using a 450 L reactor was used to extract the lignin from oil palm (<i>Elaeis guineensis</i>) empty fruit bunches (OPEFB). The acidic precipitation was achieved by adding 3% HCl until the pH reached 2, and the air bubbling was done at a rate of 2 L/min. By applying dimethylamine-acetone-formaldehyde to soda lignin in the Mannich reaction, lignin derivative was produced. The Fourier-transform infrared spectroscopy, scanning electron microscopy, and Brunauer, Emmett, and Teller methods were used to characterize all types of lignin. The analyses confirmed the formation of dimethylamine-lignin, as indicated by a 19-fold increase in the total nitrogen content in the modified lignin. Pb (II) adsorption was verified by pseudo-first-order and second-order reactions. Dimethylamine-soda lignin had the adsorption capability for lignin extracted from acid and the air bubbling technique, 6.0 and 6.8 mg/g, respectively.

Unlike many biosorbents which undergo costly modifications leading to secondary pollution risks, this research focuses on the unmodified <i>Citrus paradisi</i> (grapefruit) peel (CPP) as a promising biosorbent for Pb<sup>+2</sup> ion removal. A comprehensive analysis utilizing various techniques such as FTIR, XRD, boehm titration, point zero charge, BET, TGA, DTA, elemental analysis, AFM, and SEM–EDX was conducted on CPP shedding light on its structural and chemical properties. The biosorption process was scrutinized across multiple parameters including initial metal concentration, contact time, pH, particle size, and solution temperature. Through systematic experimentation covering a range of concentrations and temperatures, kinetic models (Pseudo first order, Pseudo second order, and Elovich) and isotherm equations (Langmuir, Freundlich, and Temkin) were applied to unveil the adsorption behavior. Remarkably, the Langmuir model revealed q<sub>max</sub> = 43.48 mg/g at 310 K and pH 5.6, underscoring the efficiency of CPP in lead removal. Further analysis employing kinetic modeling, notably the pseudo-second order model (R<sup>2</sup> = 0.999), provided insights into the rate of adsorption, affirming its effectiveness. Thermodynamic assessments unveiled an endothermic and spontaneous biosorption process onto CPP, suggesting its feasibility for lead removal in a nature-friendly manner. Moreover, the biosorption mechanism was elucidated through FTIR analysis, elucidating the molecular interactions involved.

Furthermore, for the first time, in this study subsequently regeneration of deactivated adsorbent by low-energy ultrasound waves as an inventive technique was investigated. The morphology, porosity, and crystallinity of the as-synthesized NPs were investigated by transmission electron microscopy (TEM), Scanning electron microscope (SEM), Brunauer–Emmett–Teller (BET), and X-ray diffraction (XRD) techniques. Congo red, a water-soluble azo dye, is adsorbed by nickel oxide nanoparticles, reaching about 83.20% adsorption within two hours with a pseudo-first-order rate constant of 0.0099 min<sup>−1</sup>. In the regeneration process, the nanoparticles regenerated by low-frequency ultrasound waves up to 94.35% within 35 min. The obtained data shows that the amount of regenerated nanoparticles increased with the intensity of ultrasonic irradiation. Most importantly, it can be recycled by ultrasound irradiation, which retains high performance in 3 cycles, proving its promising application for different environmental decontamination.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"154 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205589","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}
