“…Compared to frequency of C-N vibration of the acridine moiety of FFS in N-imp sol-gel material, the FTIR vibration frequencies of the C-N peak for Hg-imp were shifted slightly from 1343 to 1338 cm -1 , which might be due mainly to the formation of Hg 2? complexes with FFS in sol-gel matrix [27,28].…”

In this work, an ion-imprinted fluorescent sensor by combining sol-gel processing and spin coating was developed. Fluorescent functional silane was first synthesized and reacted with tetramethoxysilane to obtain solgel-derived materials and then used as a receptor for selective removal and sensing of Hg 2? in aqueous solution. Ion-imprinted material synthesized in the presence of Hg 2? was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, N 2 adsorptiondesorption analysis and thermogravimetric analysis by comparing with non-imprinted material obtained in the absence of Hg 2? . Surface area, pore volume and diameter were analyzed from the profile of nitrogen adsorption. It was observed that fluorescent sol-gel film exhibits distinctive change in fluorescence emission upon interaction with Hg 2? . Steady-state fluorescence experiments were performed for spectral characterization of the films, and the advancement of the reaction was defined. The shift in emission maxima and other spectral changes of the different matrices have been identified, and gelation time of sol-gel network was revealed by monitoring the emission of fluorescent silane in pre-gel solution. The corresponding selectivity factors of the imprinted fluorescent film toward Hg 2? against the other analogs were evaluated.

“…The ease of performance as well as the availability of the adsorbents, made the adsorption technique one of the most preferred extraction technique, particularly from the economic point of view [1]. Different materials such as clay [15], modified natural polymers like chitosan [16,17] and cellulose [18], in addition to modified synthetic polymer like PET [19,20] were extensively utilized as an effective adsorbents reducing the heavy metal contents in aqueous media. Among these types of adsorbents polysaccharide biopolymers such as alginate have displayed an obvious efficiency as a bio-adsorbent for such aquatic pollutants [21][22][23].…”

“…Kullanım amacına uygun çeşitli fonksiyonel gruplara sahip sentezlenmiş ve modifiye edilmiş edilmiş hidrojeller polimerik adsorban olarak kullanılabilirler. Bununla birlikte hedef iyon iyona karşı hidrojelin seçiciliği için fonksiyonel gruplar çoğunlukla yeterli olmamaktadır [1][2][3][4][5][6]. Çalışmamızda altın iyonu varlığında 4-akriloilmorfolin, 2-hidroksietil akrilat ve poli(etilenglikol)diakrilat' ın ışıkla polimerleştirilmesiyle Au(III) baskılanmış yeni bir hidrojel (Au(III)-Imp) hazırlanmıştır.…”

ÖzetBu çalışmada sulu çözeltideki altın (III) iyonu adsorpsiyonu amacıyla altın (III) iyonu baskılanmış (Au(III)-Imp) ve baskılanmamış (N-Imp) yeni hidrojeller hazırlanmıştır. Hidrojellerin fonksiyonel grupları seyreltilmiş toplam reflektans infrared spektroskopi (ATR-IR) ile araştırılmıştır. Hidrojellerin yüzey morfolojileri taramalı elektron mikroskobu (SEM) ile karakterize edilmiştir. Hazırlanan bu iyon baskılı ve baskılanmamış hidrojellerinin Au(III) iyonlarını adsorpsiyonunu etkileyen parametreler incelenerek maksimum adsorpsiyon için uygun şartlar ortam pH'ı 1, adsorpsiyon süresi 3 saat ve bu şartlar altında maksimum adsorpsiyon 500 mg/L' de 78,4 mg Au(III)/g hidrojel olarak belirlenmiştir.Anahtar kelimeler: Baskılanmış hidrojel, Au(III) iyonu, UV ile sertleşme, adsorpsiyon. Adsorption of Gold Ions from Aqueous Solution with PhotocrosslinkedMolecularly Imprinted Hydrogels AbstractIn this study, gold (III) ion-imprinted (Au(III)-Imp) and non-imprinted (N-Imp) new hydrogels was prepared for the purpose of adsorption of the aqueous solution of gold (III) ion. The functional groups of hydrogels were investigated by attenuated total reflectance infrared spectroscopy technique (ATR-IR). The surface morphologies of hydrogels were characterized by scanning electron microscopy (SEM). Au(III) ions adsorptions with Au(III)-Imp and N-Imp hydrogels was investigated and the suitable conditions for maximum adsorption was found as pH:1 and adsorption time: 3 hours. Under this conditions maximum adsorption was determined as 78.4 mg Au(III)/g hydrogel at 500 mg/L.
