“…In five consecutive tests using the membranes, the adsorption and desorption rate of the heavy metal ions remained high. Cheaper polymers such as cellulose, PVA, or PVC were also used as base polymer for electrospun membranes, which were modified to acquire heavy metal adsorption ability (Wu et al 2015;Islam et al 2015;Cai et al 2017). On the other hand, inorganic electrospun membranes, made of silica nanotubes or Hematite, were developed (Nalbandian et al 2016;Wang et al 2015).…”

Materials of nanofibrous morphology and structure are attractive for solving environmental problems including water-related issues. In recent years, increasing interest is geared on the use of specially designed electrospun nanofibers for water/wastewater treatment applications. The nanofibers can be used in the form of nonwoven structures, as stand-alone membranes, as support layer or as a surface modification layer that enables added functionality to a composite material. Continuous research has been carried out in optimizing the nanofiber membrane design and structure by manipulating material, process and surrounding parameters in the electrospinning process. This chapter highlights the recent advances and developments on the potential and application of electrospun nanofibers for water/ wastewater treatment. Comprehensive discussion is presented here on various designs and structures of nanofibers and their applications to water-related treatment and the future prospects of such materials.

“…Clays such as montomorillonite, kaoline, bentonite, attapulgite, etc., have been used as a natural cost-effective supporter for heterogeneous catalysis in wastewater treatment [22,[34][35][36]. Attapulgite (ATP), with a unique fibrous morphology, is a crystalline hydrated magnesium aluminum silicate [33].…”

A Novel Reduced Graphene Oxide-Attapulgite (RGO-ATP) Supported Fe2O3 Catalyst for Heterogeneous Fenton-like Oxidation of Ciprofloxacin: Degradation Mechanism and Pathway

Ciprofloxacin, a third-generation fluoroquinolones (FQs) antibiotic, is observed to increasingly pollute the environment. In this study, a three-dimensional reduced graphene oxide-attapulgite-based catalyst Fe2O3/RGO-ATP was prepared and used to analyze the degradation of ciprofloxacin in a heterogeneous Fenton reaction. The heterogeneous catalyst Fe2O3/RGO-ATP was prepared by a one-step hydrothermal method, and the samples were characterized using BET(Brunauer-Emmett-Teller) surface area, Raman spectroscopy, X-ray diffraction (XRD), Fourier infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The effect of reaction time, temperature, pH, initial concentration, H2O2 dosage and reuse time on the degradation of ciprofloxacin by the catalyst Fe2O3/RGO-ATP was investigated. The optimum conditions of degradation of ciprofloxacin are observed to be 60 °C, pH 5, H2O2 concentration of 2.9724 mmol/L, and initial ciprofloxacin concentration of 50 mg/L. The catalyst could be reused several times with a decline in catalytic capacity. Fourier-transform ion cyclotron resonance mass spectrometer (FT) was also employed to study the degradation products of ciprofloxacin in the aqueous solution. The results show that the heterogeneous catalyst Fe2O3/RGO-ATP possessed an excellent ability for the catalytic degradation of ciprofloxacin. Direct hydroxyl oxidation is noted to be the main pathway of degradation of ciprofloxacin, and no defluorination reaction is observed during the degradation process.

“…There are several technological approaches for preparing nanomaterials, and among these the electrospinning process is one of the most attractive methods due to its continuous fabricating capability and simple operating process [ 3 , 4 ]. The obtained materials possess high surface area to volume ratio making it suitable for various applications, such as filters [ 5 , 6 ], absorbing materials [ 7 ], textiles [ 8 ], sensors [ 9 ] and scaffolds for tissue engineering [ 10 , 11 , 12 , 13 ]. However, the application of electrospinning in the field of food packaging is still less explored [ 14 , 15 , 16 ].…”

Antimicrobial Membranes of Bio-Based PA 11 and HNTs Filled with Lysozyme Obtained by an Electrospinning Process

Bio-based membranes were obtained using Polyamide 11 (PA11) from renewable sources and a nano-hybrid composed of halloysite nanotubes (HNTs) filled with lysozyme (50 wt % of lysozyme), as a natural antimicrobial molecule. Composites were prepared using an electrospinning process, varying the nano-hybrid loading (i.e., 1.0, 2.5, 5.0 wt %). The morphology of the membranes was investigated through SEM analysis and there was found to be a narrow average fiber diameter (0.3–0.5 μm). The mechanical properties were analyzed and correlated to the nano-hybrid content. Controlled release of lysozyme was followed using UV spectrophotometry and the release kinetics were found to be dependent on HNTs–lysozyme loading. The experimental results were analyzed by a modified Gallagher–Corrigan model. The application of the produced membranes, as bio-based pads, for extending the shelf life of chicken slices has been tested and evaluated.
