Article Citation - WoS: 66Citation - Scopus: 74Preparation of Polyacrylamide Titanium Dioxide Hybrid Nanocomposite by Direct Polymerization and Its Applicability in Removing Crystal Violet From Aqueous Solution(Springer, 2023-08-02) Arslan, Dilek Senol; Ertap, Hueseyin; Senol, Zeynep Mine; El Messaoudi, Noureddine; Mehmeti, ValboneThe present paper focused on synthesizing a polyacrylamide-titanium dioxide (PAA@TiO2) nanocomposite using a cross-linking method with N, N & PRIME;-methylenebisacrylamide and then using this composite to eliminate crystal violet (CV) dye from water and to characterize the adsorbent by XRD, FT-IR, and SEM-EDX techniques. The characterization revealed that TiO2 nanoparticles dispersed homogeneously within the polymer matrix. The maximum amount of adsorption was about 38.9 mg g(-1) under the adsorbent dose of 5 g L-1, 500 mg L-1 CV dye concentration, and pH 6.9. The interaction between the CV molecule and the PAA@TiO2 nanocomposite surface was studied using Monte Carlo (MC) and molecular dynamics (MD) simulations. The negative value of the Eads (- 586.56 kcal mol(-1)) of the CV molecules onto the PAA@TiO2 nanocomposite surface gives credibility to the experimental results. All obtained results showed that PAA@TiO2 hybrid polymer nanocomposite could be an alternative adsorbent for crystal violet dye removal from wastewater.Article Gazlaştırma Tesisi Odun Atığı ve Sivas Kangal Linyit Kömürünün Boya Adsorpsiyonunda Kullanım Olanaklarının Araştırılması(Chamber of Mining Engineers of Turkey, 2020-12-01) Kırma, Ramazan; Sarikaya, Musa; Top, S.; Uçkun, Şükrü; Timür, İrfanIn this study, the usage possibilities of wood waste obtained from Gebze MDF and Particle Board Gasification Plant preliminary studies and Sivas Kangal lignite coal as absorbents were investigated. In this way, it was aimed both to evaluate the wastes and to prevent environmental pollution with materials that are cheaper and easier to obtain. The structure and surface properties of wood waste and coal samples crushed and ground to -75 µm size and used as adsorbent were investigated by XRD, SEM and BET analyses. In addition, samples have been characterized by elemental, ash, moisture, volatile matter and fixed carbon analyses. In the experiments, methylene blue (MM) with the formulation of C<inf>16</inf>H<inf>18</inf>CIN<inf>3</inf>S.xH<inf>2</inf>O was used. The effects of temperature, mixing time and concentration parameters on MM adsorption were investigated. Langmuir isotherms were created for different temperatures at optimum concentrations. As a result, it has been revealed that lignite coal and wood waste can be used as adsorbent. A 10 ppm MM for lignite coal and 3 ppm MM for wood waste were determined to be ideal concentrations for adsorption. © 2022 Elsevier B.V., All rights reserved.
