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 ...
Mechanochemically improved surface properties of activated carbon cloth for the removal of As(V) from aqueous solutions
(Elsevier, 2019)
Modified activated carbon cloth is prepared by mechanochemical modification of viscose rayon carbon cloth. The effects of different milling atmospheres, in the air and inert conditions, were investigated. Changes in kind ...
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 ...
Characterization of a low cost Lagenaria vulgaris based carbon for ranitidine removal from aqueous solutions
(Elsevier, 2017)
Practical aspects of Lagenaria vulgaris shell conversion to activated carbon were examined along with its use in ranitidine adsorption. Kinetics and isotherms of adsorption onto Lagenaria vulgaris carbon (LVC) were correlated ...
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 ...
Microwave-hydrothermal synthesis of TiO2 and zirconium doped TiO2 adsorbents for removal of As(III) and As(V)
(Elsevier, 2015)
Microwave-hydrothermal method was used for the synthesis of TiO2 and TiO2 doped with zirconium. The method was fast and simple and adsorbents were used for removal of As(III) and As(V) from aqueous solutions. The adsorbents ...
