The adsorption capacity of a biochar (BC) obtained from pine wood residues was evaluated for its ability to remove two pharmaceuticals: fluoxetine (FLX) and sulfamethizole (SMZ). material showed promising results in FLX removal, but limited the case SMZ. In order improve these results, BC surface modifications were made by doping with nitrogen, as well using acid, basic electrochemical treatments. A three-dimensional electrosorption treatment proved be most effective, increasing rate 0.45 13.46 mg/g after evaluating different operating conditions, such electrodes used or dosage. Consecutive cycles use performed through desorption electro-regeneration techniques test reuse, it observed that application 25 mA electric field increased useful life material. Finally, effect ionic strength studied, highlighting presence ions did not significantly affect efficiency SMZ although slight increase at high ion concentration, probably due salinization effect.

Fabrication of Nanocellulose/Chitosan Nanocomposite Based on Loofah Sponge for Efficient Removal of Methylene Blue: Thermodynamic and Kinetic Investigations

Journal of Inorganic and Organometallic Polymers and Materials, Год журнала: 2024, Номер unknown

Abstract We established three nano-solid adsorbents: nanocellulose based on plant loofah sponge (NC), chitosan (CS), and nanocellulose/chitosan composite (CSC). These substances were employed as solid adsorbents to eliminate methylene blue (MB) dye from wastewater. Various characterization techniques investigate all the synthesized adsorbents, including TGA (thermogravimetric analysis), XRD (X-ray diffraction spectra), (BET) nitrogen gas adsorption-desorption, SEM (scanning electron microscope), TEM (transmission microscopy), FTIR (Fourier transform infrared) spectrometer, zeta potential. According our results, CSC showed greater thermal stability than LS NC but lower CS, mesoporous (2.012 nm), higher total pore volume (0.366 cm 3 . g − 1 ), specific surface area (639.3 m 2 pH pzc of 7.22. The static adsorption MB was well described by Langmuir ( R > 0.9872), Temkin 0.9668), Dubinin-Radushkevich 0.9485) models. exhibited highest capacity (301.20 mg. ) at 47 °C after a 24 h shaking period dosage g.

The rise in population growth that necessitates an increase animal husbandry activities has led to overconsumption, improper use, and disposal of pharmaceuticals such as antibiotics leading environmental pollution. In developing countries where we have inefficient outdated wastewater treatment facilities are unable effectively remove these pollutants from domestic wastewater, the effect is contamination groundwater supply used for purposes, necessitating development advanced techniques. adoption adsorption‐based technologies with use adsorbents carbon‐based nanomaterials, biochar, functionalized nanomaterials proven be effective removing contaminants aqueous solutions. For instance, a 3D boron‐doped graphene composite been reported amitriptyline water maximum adsorption capacity 737.4 mg/g. Magnetic starch diclofenac solutions, 620.51 However, current studies limited understanding process, mechanisms, universality used. Future should focus on cost‐effective sustainable well exploring integrated approaches combine other techniques removal pharmaceutical contaminants, ensuring cleaner safer resources. To this effect, review highlights impact overconsumption compounds different thereof incorporated using method. It discusses detail various nanocomposites surface waters efficiencies.
