Adsorption characteristics of lead-, barium- and hydrogen-rich clinoptilolite mineral
(Multi-Science Publishing, 2003)The carbon dioxide and water vapour adsorption properties of local clinoptilolite-rich material, both as the original and as lead-, barium- and hydrogen-rich forms, were examined. The lead- and barium-rich forms were ... -
Adsorption of anionic polyelectrolyte and comb polymers onto lead magnesium niobate
(Elsevier, 2008-03)This paper presents the results concerning the adsorption mechanism of polyacrylic acid (PAA) and polyacrylic acid/polyethylene oxide (PAA/PEO) comb polymer onto lead magnesium niobate (PMN) powders. In the study adsorption ... -
Adsorption of NO in clinoptilolite-rich zeolitic mineral by concentration pulse chromatography method
(Elsevier, 2016-11-01)The equilibrium and kinetic parameters for NO adsorption in a clinoptilolite-rich natural zeolitic material from Turkey were determined using the concentration pulse chromatography method. Under the experimental conditions ... -
Adsorption of olive leaf (Olea europaea L.) antioxidants on silk fibroin
(American Chemical Society, 2007-02)The adsorption isotherms of oleuropein and rutin were evaluated at different temperatures, pH values, and solid/liquid ratios. The experimental data of adsorption isotherms were well fitted to a Langmuir model. The maximum ... -
Air and seawater pollution and air–sea gas exchange of persistent toxic substances in the Aegean Sea: spatial trends of PAHs, PCBs, OCPs and PBDEs
(Springer, 2015-08)Near-ground air (26 substances) and surface seawater (55 substances) concentrations of persistent toxic substances (PTS) were determined in July 2012 in a coordinated and coherent way around the Aegean Sea based on passive ... -
Air-water exchange of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) at a coastal site in Izmir Bay, Turkey
(Elsevier, 2008-02)The air-water exchange of polychlorinated biphenyl (PCB) and organochlorine pesticides (OCPs) were investigated using paired air-water samples (n = 16) collected in July and February-March, 2005 from Guzelyali Port in Izmir ... -
Alpha-pinene isomerization on acid-treated clays
(Elsevier, 2002-01)Liquid phase isomerization of α-pinene was studied over a number of differently pre-treated montmorillonite clays. The effects of the acid pre-treatment parameters (acid-to-clay ratio (A/C), water-to-acid ratio (W/A), ... -
Alumina/water suspensions in the presence of PEO-PPO-PEO triblock copolymers
(Elsevier, 2004-09)The aim of this study was to investigate the stability and dispersion behaviour of aqueous alumina suspensions in the presence of polyethylene oxide-polypropylene oxide-polyethylene oxide (PEO-PPO-PEO) type triblock ... -
Ammonium sorption by Gördes clinoptilolite rich mineral specimen
(Elsevier, 2011-12)Experimental and theoretical works were performed for the estimation of the effects of pH, initial concentration, agitation speed, particle size and temperature on the ammonium sorption by local clinoptilolite rich mineral ... -
Analytical solution of Poisson-Boltzmann equation for interacting plates of arbitrary potentials and same sign
(Elsevier, 2010-01)Efficient calculation of electrostatic interactions in colloidal systems is becoming more important with the advent of such probing techniques as atomic force microscopy. Such practice requires solving the nonlinear ... -

Ancillary effects of surfactants on filtration of low molecular weight contaminants through cellulose nitrate membrane filters
(Elsevier, 2016-03-05)Removal of contaminants with low molecular weight (<800 Dalton) requires the use of advanced separation techniques such as ultrafiltration (UF) or micellar enhanced ultrafiltration (MEUF). However, surface active agents ... -
Antibacterial and bactericidal activity of nitric oxide-releasing natural zeolite
(Elsevier, 2010-12)The zeolitic tuff from Gördes (Western Anatolia) was used as adsorbent for nitric oxide (NO) storage and release purposes. The NO loading of the zeolite was performed under 20mLmin -1 NO flow at 30°C and then the zeolite ... -
Antibacterial properties of silk fibroin/chitosan blend films loaded with plant extract
(Korean Fiber Society, 2010-03)The silk fibroin (SF)/chitosan (CHI) blend films were prepared by dissolving them in formic acid. The morphology of the films was examined by scanning electron microscopy (SEM). The roughness of the membranes was determined ... -
