Adsorption of boron on iron-oxide in aqueous solutions
(2012)
The adsorption of boron on iron-oxide (FeO(OH)) has been investigated in aqueous solutions as a function of pH, ionic strength, temperature, boron concentration and amount of the adsorbent. Analysis of the experimental ...
Adsorption of hexavalent chromium on dunite
(2011)
The paper presents and discusses the effect of various physicochemical parameters (e.g. pH, ionic strength, Cr(VI) initial concentration, amount of the adsorbent, temperature and contact time between metal ion and adsorbent) ...
Benzotriazinyl-mediated controlled radical polymerization of styrene
(2014)
The stable free radical polymerization (SFRP) process based on (1,3-diphenyl-1,4-dihydro-1,2,4-benzotriazin-4-yl), the so-called 'Blatter radical', and several C-7 substituted derivatives is introduced for the first time ...
Surface mechanism of the boron adsorption on alumina in aqueous solutions
(2013)
The adsorption of boron (boric acid) from aqueous solutions on alumina has been investigated at pH 8.0, I = 0.1 M NaClO4, T = 22 ± 3°C, and under normal atmospheric conditions. The characterization of the adsorbed species ...
Vanadium(iv/v)-p-dioxolene temperature induced electron transfer associated with ligation/deligation of solvent molecules
(2013)
Reaction of an aqueous solution of NaVO3 or a methanol solution of [VO(acac)2] with 2,5-bis((bis(2-hydroxyethyl)amino)methyl) hydroquinone, H6bdeah, results in the formation of two major vanadium species characterized by ...
Synthesis, characterization of dinuclear vanadium(III) hydroquinonate- iminodiacetate complexes
(2014)
A new VIII complex (1) of 2,5-bis[N,N-bis(carboxymethyl) aminomethyl]hydroquinone (bicah6-) was synthesized by reaction of H6bicah with two equivalents of VCl3 and six equivalents of base in aqueous solution. Crystallographic ...
Identifying potential candidates for donor-acceptor copolymers on a series of 4H-1,2,6-thiadiazines: An electrochemical approach
(2013)
A series of synthesized small organic molecules based on the 4H-1,2,6-thiadiazine moiety are studied using electrochemistry, to probe their potential as comonomer building blocks for solar-absorbing polymers for organic ...
Elucidation of mechanistic and kinetic aspects of water-gas shift reaction on supported Pt and Au catalysts via transient isotopic techniques
(2016)
With growing interest in hydrogen fuel cell applications, novel and robust water-gas shift (WGS) industrial catalysts are required with high activity, preferably at low-temperatures (To250 1C). Supported Pt and Au on ...
A comparative study of the adsorption of uranium on commercial and natural (Cypriot) sea sand samples
(2013)
The adsorption of hexavalent uranium on two different types of sea sand [e.g. a local, Cypriot (N-SS) and a commercially available marine sediment (C-SS)] has been investigated as a function of pH, initial metal concentration, ...
Emanation studies of radium containing materials by a simple radon monitoring system
(2013)
The applicability of a radon emanation system to radium determination in fine-grained solid samples has been investigated by means of a closed radon emanation system consisting of a radon monitor and an aluminium vessel. ...
