The hydrophobic aggregation of fluorite in the presence of Fe3+, Al3+, F- Ca2+, Mg2+ and Ba2+ ions was studied. Electrokinetic potentials were measured to interpret the effect of these ions on aggregation.


A comparative study of electrocoagulation and coagulation of aqueous suspensions of kaolinite powders
Kilic, Mehtap Guelsuen; Hoşten, Çetin (2010-04-15)
Removal of kaolinite particles from their synthetically prepared suspensions was studied by electrocoagulation and coagulation to investigate the effect of such operating parameters as initial pH, coagulant dosage, applied voltage, current density, and time. Coagulation was more effective in a wider pH range (pH 5-8) than electrocoagulation which yielded optimum effectiveness in a relatively narrower pH range around 9, where, in both methods, these pH values corresponded to near-zero zeta potentials of kaol...
The effect of benzo substitution on complexation of diaza 18-crown-6 ethers derivatives with NaClO4
Koylu, MZ; Demirel, N; Polat, FD; Yilmaz, A; Hosgoren, H; Balcı, Metin (Springer Science and Business Media LLC, 2005-06-01)
The complexation of the crown ethers with Na+ ion was studied. H-1-NMR chemical shifts are discussed in terms of structural modi. cation as well as also binding studies with UV-vis spectra were included.
Investigation of characteristics of urea and butyrylcholine chloride biosensors based on ion-selective field-effect transistors modified by the incorporation of heat-treated zeolite Beta crystals
Soy, Esin; Arkhypova, Valentyna; Soldatkin, Oleksandr; Shelyakina, Margarita; Dzyadevych, Sergei; Warzywoda, Juliusz; Sacco, Albert; Akata Kurç, Burcu (2012-10-01)
Urea and butyrylcholine chloride (BuChCl) biosensors were prepared by adsorption of urease and butyrylcholinesterase (BuChE) on heat-treated zeolite Beta crystals, which were incorporated into membranes deposited on ion-selective field-effect transistor (ISFET) surfaces. The responses, stabilities, and use for inhibition analysis of these biosensors were investigated. Different heat treatment procedures changed the amount of Bronsted acid sites without affecting the size, morphology, overall Si/Al ratio, ex...
The effect of boron substitution on cyclacenes
Türker, Burhan Lemi; Azizoglu, A (2001-01-15)
AM1-type semiempirical molecular orbital treatment was performed on the Huckel-type cyclacenes having certain number of boron atoms at the peri-positions and at the fusion sites of the arenoid rings. The effect of boron atoms is generally destabilizing in all the cases as compared to their unsubstituted cyclacene counterparts. The AM1 results revealed that certain properties of the boron-substituted cyclacenes are affected not only by the number of arenoid rings they have but also by the nature of their per...
The influence of polymerization temperature on structure and properties of polyaniline
Yilmaz, Faris; Kucukyavuz, Zuhal (2009-01-31)
The influence of polymerization temperature (from -25 to +25 degrees C) on molecular weight, crystallinity, electrical conductivity, thermal and morphological properties of polyaniline has been investigated. Aniline was oxidized in an aqueous medium with ammonium persulfate and 1.0 M hydrochloric acid. The reaction mixture freezes below -10 degrees C and hence lithium chloride was used in sufficient amount to prevent freezing. As the reaction temperature decreases, both the molecular weight of polyaniline a...
