“…Çeşitli membran prosesleri şu anda kimya (petrokimya gibi), ilaç, gıda ve içecek sanayide uygulamaları mevcuttur. Özellikle membran teknolojisinin güçlenmesi ve büyümesi içme suyunun üretimi ve atık suyun saflaştırılmasında gözlenmektedir (Hofman ve Pietrzak, 2013) Ağır metallerle kirlenmiş su ciddi bir çevre sorunu haline gelmiştir. Ağır metaller günlük hayatta çeşitli kaynaklardan boşaltılır ve su içinde çözüldüğünde kolayca iyonlarına oksitlenebilir (Hofman ve Pietrzak, 2013).…”

Bu çalışmada, 5,kaliks[4]aren (5) bileşiği başarıyla sentezlenmiştir. Sentezlenen bileşiğin yapısı 1 HNMR, 13 CNMR ve elementel analiz teknikleri kullanılarak aydınlatılmıştır. Elde edilen merkapto grubu bağlı kaliks[4]aren türevi, yeni bir polimer içerikli membran hazırlanması için selüloz triasetat ve 2-nitrofenil oktil eter (o-NPOE) ile birlikte katkı malzemesi olarak kullanılmıştır. Kaliks[4]aren gömülü polimer içeren membranın (KPİM) yapısı ve yüzey morfolojisi, termogravimetrik analiz (TGA) , taramalı elektron mikroskobu (SEM) , Fourier dönüşümlü kızılötesi spektroskopisi (FT-IR) ve elemental analiz teknikleri kullanılarak belirlenmiştir. Ayrıca KPİM in Zn (II), Pb (II), Co(II), Cd (II), Ni (II) ve Cu (II) iyonlarının taşıma etkinliğini değerlendirmek için Donnan diyaliz sistemi kullanılmıştır. Anahtar Kelimeler: Kaliksaren, polimer içerikli membran (PİM), eser metaller, iyon taşınması, yüzey karakterizasyonu.

“…Up to now, for removing the heavy metal contamination from water, there are some commonly adopted processes, such as chemical precipitation, ion exchange, reverse osmosis and adsorption, and so on. However, they have individual inherent limitations, such as high cost to operate, secondary contamination, and limited removal efficiency . Therefore, it is desirable to develop alternate processes and materials to remove more effectively heavy metal ions presenting in aqueous solutions.…”

3‐Hydroxy‐N,N‐diethylaniline (HDEA) as a tertiary aromatic amine was introduced onto the surface of chloromethylated polysulfone (CMPSF) microfiltration membrane through modification reaction, resulting in the modified membrane PSF‐DEA. A redox surface‐initiating system (DEA/APS) was constituted by the bonded tertiary aromatic amine group DEA and ammonium persulfate (APS) in aqueous solution, and so, the free radicals formed on the membrane initiated sodium p‐styrenesulfonate (SSS) as an anionic monomer to produce graft polymerization, getting the grafting‐type composite microfiltration membrane, PSF‐g‐PSSS membrane. Subsequently, the adsorption property of PSF‐g‐PSSS membrane for three heavy metal ions, Pb2+, Zn2+, and Hg2+ ions, was fully examined, and the rejection performance of PSF‐g‐PSSS membrane towards the three heavy metal ions was emphatically evaluated via permeation experiments. The experimental results show that by the initiating of the surface‐initiating system of DEA/APS, the graft polymerization can smoothly be carried out under mild conditions. PSF‐g‐PSSS membrane as a functional microfiltration membrane has strong adsorption ability for heavy metal ions by right of strong electrostatic interaction (or ion exchange action) between the anionic sulfonate ions on the membrane and heavy metal ions. The order of adsorption capacity is Pb2+ > Zn2+ > Hg2+, and the adsorption capacity of Pb2+ ion gets up to 2.18 μmol/cm2. As the volume of permeation solutions, in which the concentrations of the three metal ions are 0.2 mmol/L, are in a range of 50 to 70 mL, the rejection rate of PSF‐g‐PSSS membrane for the three heavy metal ions can reach a level of 95%, displaying a fine rejection and removing performance towards heavy metal ions.

“…In fact, heavy metal contamination of natural and wastewaters has become an important environmental problem, being cadmium, nickel, lead, mercury, copper and zinc the most hazardous [5,6]. Among the strategies proposal for metal ions removal from water, diffusive separation by heavy metal contaminated water passes through a membrane is a simple technique applicable to electrochemical devices.…”
