This study highlights the use of loblolly pine derived biochar for the removal of harmful algal bloom toxin, Saxitoxin (STX), from water. Biochar samples were prepared at varying pyrolysis temperatures (400, 600 and 800 °C) for 60 min. As pyrolysis temperature increases, enhancement in surface porosity was observed (SBET = 7.26 ± 0.2 m2/g to 408.15 ± 6.19 m2/g) while a decline in oxygen-containing functional groups was observed (1517.80 ± 14.98 μmol/g to 823.01 ± 7.72 μmol/g). This study aimed to discover the effects of adsorption parameters such as biochar dosage amount, contact time, initial concentration and initial pH on Saxitoxin adsorption. These studies revealed impressive results with >90 % toxin removal with dosage rate of 0.01 g/L, contact time of 30 min, and increasing percent removal with increasing initial STX concentration and initial pH in water. Maximum uptake was calculated for P400 with adsorption capacity of 314.37 μg/g. This showed that surface functionality showed higher affinity for STX uptake, which may be possible due to hydrogen bonding, electrostatic interactions, ion-exchange, and π-π interactions. Applied kinetic models indicated both physisorption and chemisorption interactions with best fit supporting the Elovich models. Complementary, adsorption isotherm analysis confirmed the multilayer adsorption behavior of the Freundlich model. Therefore, these findings support the viable use of biochar material for the remediation of STX waters.

本研究重点介绍了利用龙柏提取的生物炭去除水中有害藻华毒素--沙西毒素(STX)的方法。生物炭样品是在不同的热解温度(400、600 和 800 ℃)下经过 60 分钟制备而成的。随着热解温度的升高,观察到表面孔隙率增加(SBET = 7.26 ± 0.2 m2/g 至 408.15 ± 6.19 m2/g),同时观察到含氧官能团减少(1517.80 ± 14.98 μmol/g 至 823.01 ± 7.72 μmol/g)。这项研究旨在发现生物炭用量、接触时间、初始浓度和初始 pH 值等吸附参数对沙西毒素吸附的影响。研究结果令人印象深刻,当生物炭的用量为 0.01 克/升、接触时间为 30 分钟时,毒素的去除率大于 90%;随着水中 STX 初始浓度和初始 pH 值的增加,毒素的去除率也在增加。P400 的吸附容量最大,为 314.37 μg/g。这表明,表面官能团对 STX 的吸附具有更高的亲和力,这可能是由于氢键、静电作用、离子交换和 π-π 相互作用。所应用的动力学模型显示了物理吸附和化学吸附的相互作用,其中艾洛维奇模型的拟合效果最好。作为补充,吸附等温线分析证实了 Freundlich 模型的多层吸附行为。因此,这些研究结果支持将生物炭材料用于修复 STX 水体。

Tungsten oxide (WO3) nanoparticles (WO3NPs) were prepared using beetroot (Beta vulgaris) extract. The synthesis was optimized by evaluating the effect of pH during the reduction of the WO3 precursor and sintering temperature. Physicochemical characterization of the formed nanoparticles was performed using X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and UV-visible diffuse reflectance UV-visible spectroscopy. Furthermore, the prepared WO3NPs were employed as photocatalyst for rhodamine B removal over the photocatalytic oxidation mechanism. Synthesis optimization revealed that a single phase of WO3NPs obtained by reduction at pH 4 and a sintering temperature of 550 °C. XRD and XPS measurements revealed that the single-phase WO3NPs was obtained with a crystallite size of 26.4 nm. SEM and transmission electron microscopy (TEM) indicated polymorphic forms, predominantly as nanorods, with a mean particle size of 24 nm. The WO3NPs have a band gap energy of 2.9 eV, supporting their performance as a photocatalyst. Evaluation of the photocatalytic activities of WO3NPs represents high activity and reusability of the material. A removal efficiency of 99.67% was achieved during 30 min of treatment under UV light illumination. A study on the effect of scavengers revealed the important role of hydroxy radicals in the photocatalysis mechanism. WO3NPs can be recycled and reused for photocatalysis, maintaining photoactivity for five cycles.

Invincible growth in waste production is the consequence of overpopulation, which should be addressed to reduce the occupied landfill surface needed for their disposal and to alleviate the leachate of extremely hazardous material into the soil and water bodies. In this study, copper (Cu) was extracted from fly ash of a municipal solid waste incinerator by an electro-chemical method, which was optimized to recover the highest amount of Cu, and then it was chelated with 4-aminobenzoic acid (AM) and terephthalic acid (TM) in an aqueous phase. The obtained composites were then heated to form a porous calcinated copper-carbon composite and utilized to adsorb the forever contaminant of PFOS from aqueous solutions. As the calcinated composite of Cu/AM with a ratio of 1:1 removed a greater amount of PFOS from the aqueous solution than Cu/TA, it was utilized as the ultimate adsorbent. The platform adsorbent was subjected to multiple characterizations, including XRD, FESEM, elemental mapping, TEM, BET, EDS, ICP-OES, FTIR, DLS, and point of zero charges, as well as optimization of several operational parameters involving pH, adsorbent dosage, initial PFOS concentration, and contact time. At the neutral pH, under the optimal conditions (adsorbent dosage of 1 g L-1 and 5 h), 97.23% of PFOS was eliminated from the solution spiked with 5 mg L-1 of PFOS. The equilibrium data were best fitted with Frundlich isotherm, and the maximum adsorption capacity of 402 mg g-1 was achieved. The optimal conditions were also applied to PFOA, demonstrating high adsorption of different types of PFAS. The recovery tests of the adsorbent conducted 5 times on the solution spiked with 10 mg L-1 of PFOS showed a slight decrease in PFOS removal at least for 5 regeneration cycles, demonstrating the high adsorption capacity and its reusability, thereby validating its feasibility for large-scale applications.

人口过剩导致垃圾产量无以伦比地增长,应该解决这一问题,以减少垃圾处理所需的填埋场占地面积,并减少极度有害物质渗漏到土壤和水体中的情况。本研究采用电化学方法从城市固体废物焚化炉的飞灰中提取铜(Cu),并对该方法进行了优化,以回收最高含量的铜,然后在水相中与对氨基苯甲酸(AM)和对苯二甲酸(TM)进行螯合。然后将得到的复合材料加热,形成多孔的煅烧铜碳复合材料,用于吸附水溶液中的全氟辛烷磺酸。与 Cu/TA 相比,比例为 1:1 的 Cu/AM 煅烧复合材料能从水溶液中去除更多的全氟辛烷磺酸,因此被用作最终吸附剂。对该平台吸附剂进行了多种表征,包括 XRD、FESEM、元素图谱、TEM、BET、EDS、ICP-OES、FTIR、DLS 和零点电荷,并优化了多个操作参数,包括 pH 值、吸附剂用量、初始 PFOS 浓度和接触时间。在中性 pH 值的最佳条件下(吸附剂用量为 1 g L-1,接触时间为 5 h),添加了 5 mg L-1 PFOS 的溶液中 97.23% 的 PFOS 被消除。平衡数据与 Frundlich 等温线的拟合效果最佳,最大吸附容量为 402 mg g-1。最佳条件也适用于全氟辛烷磺酸,显示出对不同类型全氟辛烷磺酸的高吸附性。在添加了 10 mg L-1 全氟辛烷磺酸的溶液中对该吸附剂进行了 5 次回收测试,结果表明至少在 5 个再生周期内,全氟辛烷磺酸的去除率略有下降,这表明该吸附剂具有很高的吸附能力和可重复使用性,从而验证了其大规模应用的可行性。

In this study, copper (Cu) was extracted from fly ash of a municipal solid waste incinerator by an electro-chemical method, which was optimized to recover the highest amount of Cu, and then it was chelated with 4-aminobenzoic acid (AM) and terephthalic acid (TM) in an aqueous phase. The obtained composites were then heated to form a porous calcinated copper-carbon composite and utilized to adsorb the forever contaminant of PFOS from aqueous solutions. As the calcinated composite of Cu/AM with a ratio of 1:1 removed a greater amount of PFOS from the aqueous solution than Cu/TA, it was utilized as the ultimate adsorbent. The platform adsorbent was subjected to multiple characterizations, including XRD, FESEM, elemental mapping, TEM, BET, EDS, ICP-OES, FTIR, DLS, and point of zero charges, as well as optimization of several operational parameters involving pH, adsorbent dosage, initial PFOS concentration, and contact time. At the neutral pH, under the optimal conditions (adsorbent dosage of 1 g L<sup>-1</sup> and 5 h), 97.23% of PFOS was eliminated from the solution spiked with 5 mg L<sup>-1</sup> of PFOS. The equilibrium data were best fitted with Frundlich isotherm, and the maximum adsorption capacity of 402 mg g<sup>-1</sup> was achieved. The optimal conditions were also applied to PFOA, demonstrating high adsorption of different types of PFAS. The recovery tests of the adsorbent conducted 5 times on the solution spiked with 10 mg L<sup>-1</sup> of PFOS showed a slight decrease in PFOS removal at least for 5 regeneration cycles, demonstrating the high adsorption capacity and its reusability, thereby validating its feasibility for large-scale applications.</p>","PeriodicalId":93933,"journal":{"name":"Chemosphere","volume":" ","pages":"143963"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142857344","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}
