Article Citation - WoS: 1Exploring Mil-53 (al) Adsorption Efficiency for Indigo Carmine Dye(Konya Teknik Univ, 2024-03-18) Yanardağ Kola, Duygu; Edebalı, Serpil; Kola, Duygu YanardagSynthetic dyes are extensively used in industrial areas, including plastic, textile, and food. However, they are a major environmental problem due to their negative effects on water quality and living organisms. To address one of these problems, MIL-53 (Al) is served as an adsorbent for removing indigo carmine dye, being widely used in textile industries. The synthesis of MIL-53 (Al) was carried through the hydrothermal method and different synthesis conditions were studied to find the best adsorbent to remove indigo carmine. FTIR, XRD, SEM, and EDS were used to assess materials. Isotherm models and kinetic models were investigated for indigo carmine adsorption, revealing that the Langmuir isotherm model and pseudo-second-order kinetic model provided best fit to data. The highest adsorption capacity was calculated as 145 mg/g. The study contributes valuable insights into the adsorption of indigo carmine by MIL-53 (Al).Article Citation - WoS: 30Citation - Scopus: 32Adsorptive Removal of Malachite Green Dye From Aqueous Solution by Ion Exchange Resins(Springer Science and Business Media Deutschland GmbH, 2023-09-09) Yanardağ, D.; Edebali, S.The adsorption of malachite green dye by commercially available synthetic polymers Diaion CR-11 and Amberlite IRC-748 resins has been studied. The effect of the initial dye concentrations, adsorbent dosage, contact time, pH, and temperature were examined. The dye adsorption mechanism for both resins was investigated using Langmuir, Freundlich, Scatchard, and Dubinin-Radushkevich (D-R) isotherm models. Also, experimental data were applied to the pseudo-first-order and pseudo-second-order kinetic models. The Langmuir isotherm and pseudo-second-order kinetic model best fit to the equilibrium data showed maximum adsorption capacities of 102.1 mg/g and 480.6 mg/g for Diaion CR-11 and Amberlite IRC-748, respectively. Thermodynamic studies show that the adsorption of malachite green dye increases with temperature and indicates that the adsorption process of both resins is endothermic. The negative value of change in Gibbs free energy shows spontaneous adsorption of malachite green on both resins. The polymer resins are characterized by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM). © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.Article Citation - WoS: 6Citation - Scopus: 5Facile Synthesis of Zeolitic-Imidazole Framework-67 (zif-67) for the Adsorption of Indigo Carmine Dye(John Wiley and Sons Inc, 2024-09-24) Kola, D.Y.; Edebali, S.the authors reviewed and edited the content as needed and took full responsibility for the content of the publication.Article Citation - WoS: 21Citation - Scopus: 21Pecvd Application To Obtain Polymer Coated Graphene Nanoplatelets and Development of New Epoxy Nanocomposites(Budapest Univ Technol & Econ, 2022) Yanardağ, Duygu; Ahmetli, Gülnare; Karaman, Mustafa; Kocaman, SüheylaIn this study, graphene nanoplatelets (GNPs) were synthesized from graphite by a liquid-phase exfoliation (layer separation) method, and their surfaces were functionalized with poly(glycidyl methacrylate) (PGMA) by using the rotating bed plasma-enhanced chemical vapor deposition (PECVD) method. Fourier-transform infrared spectroscopy (FT-IR), Raman spectroscopy, scanning electron microscopy (SEM), X-ray powder diffraction (XRD), and thermogravimetric (TGA) analyses were performed to characterize the unmodified (u-GNP) and modified GNP (PGMA-GNP). Epoxy nanocomposites were prepared with both types of GNPs at different loading levels (0.1-2% by weight). The role of the surface modification of the GNPs on the mechanical, thermal, electrical conductivity, contact angle, water sorption, and corrosion properties of the epoxy nanocomposite coatings was also investigated. Consequently, the tensile strength and Young's modulus of the epoxy resin (ER)/PGMA-GNP nanocomposites were enhanced by 10.2-20 and 3.3-18.4%, respectively, as compared to the ER/u-GNP composites. Moreover, the nanocomposites prepared with PGMA-GNP had better water sorption and wettability properties than those prepared with u-GNP, but lower electrical conductivity. The corrosion test results showed that the addition of GNPs to epoxy effectively improved the corrosion resistance of the epoxy composites in high salinity, basic, and acidic environments.Article Citation - WoS: 14Citation - Scopus: 14Ciprofloxacin Adsorption Performance of Co-Doped Uio-66(Wiley, 2023-11-14) Yanardağ, Duygu; Güzel Kaya, Gülcihan; Edebali, Serpil; Kaya, Gulcihan GuzelThe presence of ciprofloxacin in various water sources, even at low concentrations, causes health risks and serious environmental pollution as well as development of antibiotic resistance. So, it is critically necessary to remove ciprofloxacin effectively from the effluent. Co-doped UiO-66 was synthesized through one-step hydrothermal method and evaluated as an adsorbent for ciprofloxacin adsorption. Ciprofloxacin adsorption was systematically investigated revealing adsorption isotherms, kinetics, and thermodynamics. The findings revealed that Freundlich isotherm model (maximum adsorption capacity: 45.17 mg g-1) at optimum experimental conditions (pH: 5, contact time: 90 min and adsorbent dosage: 0.3 g L-1) and acquired data were fitted using pseudo-second-order kinetic model. The ciprofloxacin adsorption was determined to be a spontaneous and endothermic from thermodynamic experiments. Effects of coexisting compound in the aqueous solutions on the Co-doped UiO-66 adsorption performance were studied using different concentrations of NaCl solution. The ciprofloxacin removal slightly decreased in the case of increasing the concentrations of Na+ ions. Regeneration of the Co-doped UiO-66 was carried out in methanol + acetic acid solution and repeated adsorption experiments were conducted to reveal reusability of the Co-doped UiO-66. Its ciprofloxacin adsorption capacity reduced to 38.0 mg g-1 after the four cycles indicating that the Co-doped UiO-66 was a reusable and potential adsorbent for ciprofloxacin adsorption process. Co-doped UiO-66 was evaluated as an adsorbent for ciprofloxacin removal from aqueous solutions. High ciprofloxacin adsorption capacity was achieved through the various adsorption mechanisms. Repeated adsorption-desorption cycles showed the Co-doped UiO-66 sample was a promising reusable adsorbent for ciprofloxacin adsorption processes.imageConference Object Advanced Oxidation Processes for Degradation of Pharmaceuticals Used During Covid-19 Pandemic(Elsevier, 2024) Ramirez, I.; Mariam, E.; Kumar, A.; Yanardağ, D.; Villaseñor-Basulto, D.L.; Garcia-Huante, Y.G.; Ordaz, A.; Rowles, Lewis S.The COVID-19 pandemic impacted public health, the economy, and the environment worldwide. During the pandemic, high demand for prescribed pharmaceuticals to treat COVID-19 and other consequential illnesses was observed, including antiviral, corticosteroids, antidepressants, analgesics, and antibiotics. The excessive use of these pharmaceutical compounds provoked new concerns regarding their presence in water bodies. Although the concentrations of these compounds in water are in trace levels (e.g., ng L−1 in most cases), the scientific community has classified them as emerging contaminants of paramount importance. Wastewater and drinking water systems have been encouraged and, in some cases, required to remove these emerging contaminants. Among various treatment techniques, advanced oxidation processes (AOPs) are potential technologies to degrade and remove these contaminants. AOPs represents a broad group of treatment processes for oxidizing compounds that are typically resistant to conventional redox processes. In this chapter, the impact of COVID-19 on water systems is discussed to understand the current circumstances of associated pharmaceutical compounds. We explore the effectiveness of AOPs from the lens of removing these organic molecules. In addition, we provide an overview of the current methods for the detection and quantification of pharmaceutical compounds against COVID-19 in wastewater. The information presented in this chapter has the potential to help engineers, scientists, and public health professionals navigate how AOPs can be used for degradation of pharmaceuticals in water. © 2024 Elsevier Inc.
