    Incorporation of Iron Nanoparticles Into Clinoptilolite and Its Application for the Removal of Cationic and Anionic Dyes
    (Korean Society of Industrial Engineering Chemistry, 2015) Eroğlu, Ahmet Emin; Shahwan, Talal; Shahwan, Talal; Fuchs, Harald; 04.01. Department of Chemistry; 04. Faculty of Science; 01. Izmir Institute of Technology
    This study reports the preparation of composite sorbents of iron nanoparticles (nZVI) and clinoptilolite at various iron/clinoptilolite ratios. The composites were characterized using various characterization techniques. The material was used for the removal of methylene blue (MB) and methyl orange (MO) as model cationic and anionic dyes. The experiments investigated the effects of time, loading, initial pH, reusability, and temperature on the removal process. According to the results, Cl-nZVI showed fast and quantitative removal over a wide range of concentrations. The removal process was endothermic in nature, and the composite demonstrated reusability for several trials.

    Removal of Aqueous Rare Earth Elements (rees) Using Nano-Iron Based Materials
    (Korean Society of Industrial Engineering Chemistry, 2013) Ünal Yeşiller, Semira; Eroğlu, Ahmet Emin; Shahwan, Talal; Eroğlu, Ahmet Emin; 04.01. Department of Chemistry; 04. Faculty of Science; 01. Izmir Institute of Technology
    The uptake of REEs was investigated using nano-zero valent iron (nZVI) and alumina-supported nZVI (Al-nZVI). The results indicated fast uptake, with saturation approached within 10 min of contact between solutions and solids. Upon using nZVI, the uptake of REEs seemed to be quantitative over the studied range of concentration; 1.0–100.0 mg L−1. When Al-nZVI was used, complete removal was achieved within the range of 1.0–10.0 mg L−1. The solids demonstrated stable performance beyond pH of 2.0, up to neutral pH conditions. Fractionation of REEs on Al-nZVI was observed. The REE ions seem to be fixed to oxide and oxyhydroxide surface groups.
