The molecular aggregation of pyronin y in natural bentonite clay suspension
(Elsevier, 2011)The molecular aggregation and spectroscopic properties of Pyronin Y (PyY) in the suspension containing natural bentonite clay were studied using molecular absorption, steady-state and time-resolved fluorescence spectroscopy ... -
Newly synthesized bentonite-histidine (Bent-His) micro-composite affinity sorbents for IgG adsorption
(Elsevier, 2007)Bentonite has several advantages for use as a support, including its lack of toxicity, chemical reactivity and hydrophilicity allowing easy fixation of biomolecules. A new approach was developed to obtain an efficient and ... -
Performance of magnesium oxide-coated bentonite in removal process of copper ions from aqueous solution
(Elsevier, 2010)This paper presents the adsorption of Cu(II) ions from aqueous solution on modified Unye bentonite. Adsorption of Cu(II) ions by magnesium oxide-coated bentonite (MCB) sample was investigated as a function of the initial ... -
Photophysical and adsorption properties of pyronin B in natural bentonite clay dispersion
(Elsevier Science Bv, 2015)The present study focused on the adsorption and photophysical properties of pyronin B (PyB) in bentonite aqueous dispersion. the photophysical properties of PyB in the aqueous dispersion were studied by using UV-vis ... -
Reversible immobilization of catalase by using a novel bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents
(Elsevier, 2008)This study focused on developing bentonite-cysteine (Bent-Cys) microcomposite affinity sorbents (38-105 ?m) for catalase adsorption from aqueous solutions. Pseudo-biospecific affinity ligand l-cysteine was covalently binded ... -
Structural characterization of aniline-bentonite composite by FTIR, DTA/TG, and PXRD analyses and BET measurement
(Taylor & Francis, 2011)The aniline species incorporated into the acid-activated bentonite matrices leads to the decay of the skeletal stretches centered at 1041 cm-1 and the rise of new features in the phenyl ring frequency region, 1700-1400 ... -
Ünye bentonitin naproksen ve pyronin Y ile etkileşmelerinin XRD, FTIR, UV-GÖR, BET, termik analiz ve floresans teknikleri yardımıyla aydınlatılması
(Rize Üniversitesi / Fen Bilimleri Enstitüsü / Kimya Anabilim Dalı, 2010)Bu çalışmada, Ünye Bentonit ile bir ilaç etken maddesi olan Naproksen ve lazer boyası olarak kullanılan Pyronin Y moleküllerinin etkileştirilmesiyle sentezlenen kompositlerin termal kararlılık ve yapısal özellikleri ... -
Ünye-bentonit/poliakrilamid (PAAM) hidrojel kompozitlerin sentezi ve karakterizasyonu
(Rize Üniversitesi / Fen Bilimleri Enstitüsü / Kimya Anabilim Dalı, 2011)Kontrollü ilaç salınımı, biyouyumlu malzeme, ayırma membranı ve tarımsal amaçlı olarak kullanılan hidrojeller pH, sıcaklık ve manyetik alan gibi faktörlerden etkilenerek su alıp şişebilen çapraz bağlı polimerik ağ yapılardır. ...
