Abstract
Carbonaceous materials have been widely applied as adsorbents, but there are some factors that affect their efficiency. In this context, advances in nanotechnology provide new and more efficient methodologies for water treatment. This study evaluated the efficiency of a novel carbon-based adsorbent developed from Brazilian polyacrylonitrile textile fiber and functionalized with iron oxide magnetic nanoparticles for the removal of 2,4-dichlorophenoxyacetic acid (2,4-D) from the aqueous medium. The synthesized adsorbent (ACF-Fe3O4) was characterized by FTIR, XRD, VSM, Zeta potential, SEM, EDX, and TEM. The characterization techniques showed that the adsorbent has peaks characteristic of its precursors and superparamagnetic characteristics, confirming the efficiency of the synthesis method. The adsorption tests evaluated the influence of adsorbent dosage, pH of the contaminant solution, contact time and temperature on the removal of 2,4-D. The experimental data were better adjusted by the pseudo-second order kinetic model and by the Langmuir isothermal model. The thermodynamic parameters revealed that the process is exothermic, spontaneous and thermodynamically favorable. Under the best experimental conditions, the maximum adsorption capacity obtained was 51.10 mg g-1 with an adsorbent concentration of 0.33 g L-1, natural pH of the solution, temperature of 288 K at the equilibrium time of six hours. Adsorbent reusage was studied in four desorption cycles. The adsorption mechanism can be explained through π-π bonds, hydrogen bonds and electrostatic interactions. The prepared material presented high-efficiency adsorption capacity of 2,4-D compared to other carbonaceous materials present in the literature, demonstrating its viability for the removal of this contaminant from the aqueous medium.

Efficacy of an organically modified bentonite to adsorb 2,4-dichlorophenoxyacetic acid (2,4-D) and prevent its phytotoxicity. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2021; 297:113427. [PMID: 34346399 DOI: 10.1016/j.jenvman.2021.113427] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 07/25/2021] [Accepted: 07/27/2021] [Indexed: 06/13/2023]
Abstract
The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is widely used due to it selective action, and preferential control of dicotyledonous weeds affecting cereal crops. Physiological responses of sensitive dicotyledonous plants to 2,4-D include growth retardation, senescence, and cell death. Due to soil and water contamination by agricultural practices, 2,4-D constitutes a potential risk to non-target plant species. In this work, the potential advantage of using organic modified bentonite (Bent) to adsorb 2,4-D and therefore mitigate damage produced by this herbicide on sensitive not-target vegetable species was investigated. Dodecylamine (DDA) was used as an organic modifier to change the hydrophilic nature of Bent into an organophilic matrix. The adsorption performances of 2,4-D by Bent-DDA were analyzed. The maximum adsorptions of 2,4-D (22.1 mg/L) from aqueous solution containing 1.0 or 2.5 mg/mL Bent-DDA were 40 and 80 %, respectively. The physical interaction of Bent-DDA with 2,4-D was characterized by Wide Angle X-ray Scattering (WAXS) and thermogravimetric analysis (TGA). The biological functionality of Bent-DDA matrix as 2,4-D adsorbent was tested in a bioassay in the Arabidopsis thaliana plant model system. The primary root growth of Arabidopsis seedlings is strongly inhibited by low concentrations of 2,4-D. Arabidopsis seedlings submitted to Bent-DDA pre-treated herbicide aqueous solution showed similar root growth than 2,4-D non-treated seedlings. Finally, the ability of Bent-DDA to prevent 2,4-D phytotoxicity was exploratory investigated in lettuce plants. Lettuce plants pre-treated with 20 μg/mL Bent-DDA showed reduced sensitivity to 2,4-D including an increment on chlorophyll content and biomass compared with non-treated plants. Our findings revealed a promising scenario for the application of Bent-DDA as an effective adsorbent of 2,4-D at productive scale.

Potential of multisyringe chromatography for the on-line monitoring of the photocatalytic degradation of antituberculosis drugs in aqueous solution. CHEMOSPHERE 2015; 121:68-75. [PMID: 25434276 DOI: 10.1016/j.chemosphere.2014.11.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/29/2014] [Revised: 11/04/2014] [Accepted: 11/05/2014] [Indexed: 06/04/2023]
Abstract
In this study, a multisyringe chromatography system (MSC) using a C18 monolithic column was proposed for the on-line monitoring of the photocatalytic degradation of isoniazid (INH, 10 mg L(-1)) and pyrazinamide (PYRA, 5mgL(-1)) mixtures in aqueous solution using a small sample volume (200 μL) with an on-line filtration device in a fully automated approach. During the photocatalytic oxidation using TiO2 or ZnO semiconductor materials, total organic carbon (TOC) and the formed intermediates were analyzed off-line using ion chromatography, ion exclusion HPLC, and ESI-MS/MS. The results showed that TiO2 exhibits a better photocatalytic activity than ZnO under UV irradiation (365 nm) for the degradation of INH and PYRA mixtures, generating 97% and 92% degradation, respectively. The optimal oxidation conditions were identified as pH 7 and 1.0 g L(-1) of TiO2 as catalyst. The mineralization of the initial organic compounds was confirmed by the regular decrease in TOC, which indicated 63% mineralization, and the quantitative release of nitrate and nitrite ions, which represent 33% of the nitrogen in these compounds. The major intermediates of INH degradation included isonicotinamide, isonicotinic acid, and pyridine, while the ESI-MS/MS analysis of PYRA aqueous solution after photocatalytic treatment showed the formation of pyrazin-2-ylmethanol, pyrazin-2-ol, and pyrazine. Three low-molecular weight compounds, acetamide, acetic acid and formic acid, were detected during INH and PYRA decomposition. PYRA was more resistant to photocatalytic degradation due to the presence of the pyrazine ring, which provides greater stability against OH attack.
