Detection limit for an adsorption-based mercury sensor
(Elsevier, 2013)
A novel readout procedure for the determination of detection limit at an adsorption-based mercury sensor is described. The procedure is based on the evaluation of the initial voltage slope in time evolution of adsorbed ...
Chromium (VI) removal from aqueous solutions using mercaptosilane functionalized sepiolites
(Elsevier, 2011)
Natural and acid-activated sepiolite samples were functionalized with (3-Mercaptopropyl)trimethoxysilane.
By X-ray powder diffraction, Fourier transform infrared spectroscopy, and differential thermal
analysis it was ...
Removal of Tc-99(VII) by organo-modified bentonite
(Elsevier, 2014)
(99)Technetium is one of the largest components of nuclear waste material. In aqueous solutions Tc-99 is present as the pertechnetate oxoanion, (TcO4-)-Tc-99, which is highly soluble and mobile in groundwater under oxidizing ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Elsevier, 2010)
The concept of higher-order frequency response functions(FRFs), which is based on Volterra series representation of nonlinear systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
Inorganically modified diatomite as a potential prolonged-release drug carrier
(Elsevier, 2014)
Inorganic modification of diatomite was performed with the precipitation product of partially neutralized aluminum sulfate solution at three different mass ratios. The starting and the modified diatomites were characterized ...
Polyaniline and its composites with zeolite ZSM-5 for efficient removal of glyphosate from aqueous solution
(Elsevier, 2013)
Nanostructured and granular polyanilines (PANIs) and their composites with zeolite ZSM-5, synthesized by the oxidative polymerization of aniline in water and aqueous solution of sulfuric acid, are evaluated as adsorbents ...
Adsorption of lipase from Candida rugosa on multi walled carbon nanotubes
(Korean Society of Industrial Engineering Chemistry, 2013)
In this work lipase from Candida rugosa was adsorbed on unmodified surface of multi walled carbon nanotubes (raw-MWCIsIT). The effects of immobilization time, initial enzyme concentration and buffer ionic strength on enzyme ...
Simultaneous photodegradation of two textile dyes using TiO2 as a catalyst
(Springer Netherlands, 2016)
The simultaneous photocatalytic degradation of two dyes: methylene blue (MB), a cationic dye, and arylazo pyridone dye (SD), an anionic dye was investigated using sol-gel prepared TiO2 particles. The paper shows the main ...
Fluctuations in transient response of adsorption-based plasmonic sensors
(Elsevier, 2014)
The basic parameters of a sensor element defining its ultimate performance are sensitivity and intrinsic noise. In plasmonic gas sensors both are determined by refractive index changes due to adsorption and desorption (a-d) ...
Organo-inorganic bentonite for simultaneous adsorption of Acid Orange 10 and lead ions
(Elsevier, 2010)
Partial substitution of the interlayer cations of a local bentonite (Bogovina) by hexadecyl trimethylammonium ions (HDTMA) was performed to prepare adsorbents able to simultaneously adsorb toxic metal cations and organic ...
