“…Electrochemical processes, exchanging ions, flotation, coagulation-flocculation, biotic processing, adsorption, reverse osmosis, as well as separation membranes, were widely used for the elimination of organic and inorganic pollutants [10][11][12][13][14][15][16]. However, the adsorption technique is the most widely used technique among all methods due to its cheapness, simplicity, and effectiveness [17].…”

Because of its effectiveness in organic pollutant degradation, manganese peroxidase (MnP) enzyme has attracted significant attention in recent years regarding its use for wastewater treatment. Herein, MnP was extracted from Anthracophyllum discolor fungi and immobilized on the surface of magnetic nanocomposite Fe 3 O 4 /chitosan. The prepared nanocomposite offered a high surface area for MnP immobilization. The influence of several environmental factors like temperature, pH, as well as storage duration on the activity of the extracted enzyme has been studied. Fourier transmission infrared spectroscopy (FT-IR), scanning electron microscope (SEM), X-ray diffraction (XRD), and transmission electron microscope (TEM) techniques were used for the characterization of the prepared MnP/Fe 3 O 4 /chitosan nanocomposite. The efficiencies of the prepared MnP/Fe 3 O 4 /chitosan nanocomposite for the elimination of reactive orange 16 (RO 16) and methylene blue (MB) industrial dyes were determined. According to the results, the immobilization of MnP on Fe 3 O 4 /chitosan nanocomposite increases its capacity to decolorize MB and RO 16. This nanocomposite allowed the removal of 96% ± 2% and 98% ± 2% of MB and RO 16, respectively. The reusability of the synthesized nanocomposite was studied for five successive cycles showing the ability to retain its efficiency even after five cycles. Thus, the prepared MnP/Fe 3 O 4 /chitosan nanocomposite has potential to be a promising material for textile wastewater bioremediation.

Organic arsenic compounds in the environment are a global threat to human health. This threat has created the urgency to develop highly efficient adsorbents with both high adsorption capacity and versatile removal of different arsenic compounds. A novel 1D zinc(II) coordination polymer, formulated as Zn2(datrz)2(bpy)Cl2 (BUC‐70) (datrz = guanazole, bpy = 4,4′‐bipyridine), was successfully synthesized through slow evaporation at room temperature. BUC‐70 exhibited an excellent adsorption capacity toward p‐arsanilic acid (p‐ASA) and roxarsone (ROX) in water, which could be ascribed to As–O–Zn bonding interactions and strong hydrogen‐bonding interactions between the organic arsenics and BUC‐70. The maximum adsorption capacities toward p‐ASA and ROX were 738 and 937 mg·g−1, respectively. BUC‐70 was effective in the removal of p‐ASA and ROX at low concentrations (<5 mg·l−1) from the simulated p‐ASA and ROX wastewater. Furthermore, the as‐synthesized BUC‐70 exhibited good adsorption property toward p‐ASA and ROX in wastewater simulated by lake water and tap water. After adsorptive treatment using BUC‐70, the concentrations of both p‐ASA and ROX were lower than the required concentrations of the drinking water standard of the World Health Organization and the surface water standard of China. Continuous‐flow, fixed‐bed column experiments were performed using BUC‐70 loaded on cotton as packing material to explore the potential large‐scale application.

“…However, the lower utilization rate causes that more than 70% of tetracycline would be excreted in urine and feces of humans and animals and released into the environment [15]. As far as we know, various adsorption materials have been developed to remove TC from aqueous solution, such as clay minerals [19][20][21], zeolites composites [22,23], graphene oxide (GO) [24], multi-walled carbon nanotubes (MWC-NTs) [25], biochar [26][27][28][29][30], covalent-organic frameworks (COFs) [31], metal-organic frameworks (MOFs) [32][33][34][35][36] and their composites [37][38][39][40][41]. Among these adsorbent materials, MOFs, composed of organic linkers and metallic clusters, are a new class of porous materials.…”

MOF-818, a mesoporous cage metal-organic framework, was investigated for the removal of tetracycline hydrochloride (TC) from aqueous environment. The product was characterized by XRD, BET, FESEM, FT-IR, XPS and TGA. The influence of different parameters such as solution pH, contact time, temperature, adsorption dosage, initial TC concentration on the adsorption capacity was investigated. The as-prepared MOF-818 showed rapid removal of TC and with maximum saturated adsorption capacity calculated to be 442.5 mg g −1 at pH 3.32, 323 K. The adsorption isotherms were fitted by Langmuir, and Freundlich models. The kinetic data was analyzed by pseudo-first-order, pseudo-second-order, and intraparticle diffusion models. The TC adsorption process followed pseudo-second-order kinetics and best fitted the Langmuir adsorption model. The thermodynamic data showed that the adsorption was a spontaneous and endothermic reaction. A mechanism for TC adsorption was proposed and the chemisorption and π-π interaction was believed to direct the interaction between MOF-818 and TC molecules.
