Effect of hydrocarbon chain length on adsorption of cationic surfactants onto clinoptilolite
(Elsevier, 01.01.2003)
The adsorption behavior of quaternary ammonium cationic surfactants with different
hydrocarbon chain lengths, i.e. HDTMA (hexadecyltrimethylammonium), TDTMA (tetradecyltrimethy-
lammonium) and DDTMA (dodecyltrimethylammonium), ...
Effects of La2O3 addition on the thermal stability of γ-Al2O3 gels
(Elsevier, 01.01.2004)
The effects of La2O3 additions up to 5 wt.% on the thermal stabilities of sol-gel derived alumina gels were studied. Observations
were made on pore size, total pore area, phase changes at various sintering temperatures ...
Investigation of equilibrium, kinetic, thermodynamic and mechanism of basic blue 16 adsorption by montmorillonitic clay
(Springer, 20.02.2013)
The adsorption of a cationic dye, Basic Blue 16
(BB16), by montmorillonitic clay was studied in detail.
Changes in the molecular structure during adsorption were
analyzed by FTIR spectroscopy. BB16 adsorption onto ...
Influence of pH and chloride-based metal salts on coagulation/dispersion behavior of talc suspension
(Separation Science and Technology, 01.05.2011)
In this study, the coagulation behavior of talc suspensions in the
presence and absence of chloride-based metal salts (NaCl, CaCl
and AlCl
) at a constant (pH 4) and different pHs was assessed
by sedimentation tests ...
Turbidity removal from wastewaters of natural stone processing by coagulation/flocculation methods
(WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 17.04.2009)
The effectiveness of coagulation (at pH values of 6, 7.5, and 9), flocculation (at pH 9),
and coagulation plus flocculation (at pH 9) on turbidity removal from natural stone
(travertine) processing wastewaters (NSPW) ...
Effect of pH and polymer charge density on settling rate and turbidity of natural stone suspensions
(Elsevier, 02.02.2005)
In the present paper, the effects of suspension pH and charge density of anionic polyacrylamide (PAA) on flocculation
behavior of two different natural stone suspensions (NSS) marble and travertine were investigated by ...

Influence of dry grinding on physicochemical and surface properties of talc
(Oficyna Wydawnicza Politechniki Wrocławskiej, 01.02.2017)
In this study the effect of dry grinding on hydrophobicity, surface free energy (SFE), particle size distribution, surface area, porosity, oil absorption, and whiteness of talc was investigated. The dry grinding was performed ...
Adsorption of Cr(VI) Ions on Magnetite Nano-Particles (Fe3O4): Kinetic and thermodynamic studies
(El-Cezerî Journal of Science and Engineering, 01.10.2016)
This article intends to investigate the kinetic and thermodynamic properties of adsorption process of hexavalent chromium [Cr(VI)] ions on magnetite nano-particles (Fe 3 O , MNPs). In accordance with this purpose, MNPs ...
Vector-valued bivariate entire functions of bounded index satisfying a system of differential equations
(2018)
The concept of complex valued bivariate entire functions of bounded index is extended to
C^n valued bivariate entire functions by replacing the absolute value in the definition of an entire
function of bounded index by ...
