Article Citation - WoS: 29Citation - Scopus: 34Preparation and Characterization of a Novel Diatomite-Based Composite and Investigation of Its Adsorption Properties for Uranyl Ions(Springer, 2019-07-20) Senol, Zeynep Mine; Arslan, Dilek Senol; Simsek, Selcuk; Şenol Arslan, DilekIn this research, Polyacrylamide-diatomite (PAA-D) composite was used as adsorbent for the efficient removal of uranyl ions from aqueous solution. The chemical and morphological properties of PAA-D composite were confirmed by several analysis. Batch experiments were performed as a function of solution pH, initial concentration, kinetic, thermodynamic and recovery. The maximum metal uptake capacity was found as 0.085 mol kg(-1). Kinetic data were best interpreted by a pseudo second order model. Thermodynamic findings showed that the adsorption process was exothermic, spontaneous and process with increased disorderliness at solid/solution interface. The recovery studies showed that PAA-D composite had good adsorption/desorption performance.Article Türkiye’de Farklı Yörelerde Bulunan Kolemanit Minerallerinin Fiziksel, Kimyasal Ve Termal Özelliklerinin Tayini(Gumushane University, 2021-08-24) Senol-Arslan, Dilek; Arslan, Dilek Senol; Şenol Arslan, DilekIn this study, colemanite is an important boron mineral which constitutes about 76% of Turkey's boron reserves, is frequently used in applications obtained as a result of scientific and technological developments. In this context, a detailed literature survey was carried out colemanite minerals. Characteristic and structural features of the colemanite samples of four different regions (Kestelek, Emet (Hisarcık, Espey), Bigadiç regions) were determined by analyzes such as X-Ray Diffraction (XRD), Inductively Coupled Plasma, ICP and Mass Spectrometry, MS (ICP-MS), Thermogravimetric and Differential thermal analysis (TG-DTA), and Fouier Transform Infrared Spectroscopy (FT-IR) methods. In line with these findings, the mineralogical, chemical and thermal properties of pure colemanite crystals were determined and the similarities and differences between the samples were revealed. © 2025 Elsevier B.V., All rights reserved.
