Determination of the surface properties of untreated and chemically treated kaolinites by inverse gas chromatography
(2006)
Inverse gas chromatography is used to study the surface properties of the untreated and chemically treated kaolinite samples. Changes in the enthalpy of adsorption for a variety of probes and in the surface energy of clays ...
Investigation of Pd-catalyzed Co(III)-EDTA/hypophosphite inhibition reaction kinetics, mechanism and the evaluation of its analytical application possibilities
(Serbian Chemical Society, 2004)
The reaction between Co(III)-EDTA and hypophosphite ion, catalyzed by Pd(II) was chosen as the indicator reaction. The inhibition kinetics of this catalytic reaction have been investigated by a mechanistic approach in the ...
Evaluation of the thermodynamic parameters for the adsorption of some hydrocarbons on chemically treated-bentonites by inverse gas chromatography
(2005)
Inverse gas chromatography has been used to evaluate the adsorption parameters (?H a, ?H st, ?S a and ?G a) of some probe molecules, each representing a class of organic (n-hexane, cyclohexane, benzene, n-octane, 1-octene ...
Kinetic spectrophotometric determination of trace amounts of selenium based on the catalytic reduction of maxilon blue-SG by sulfide
(Elsevier Inc., 2003)
A simple and sensitive catalytic spectrophotometric method was developed for the determination of trace amounts of selenium. The method is based on the catalytic effect of selenium in form Se(IV) on the reduction of Maxilon ...
Determination of sodium and potassium in certified rock samples by AES after ultrasonic leaching
(2006)
In order to evaluate the data obtained by atomic emission spectrometric analysis after ultrasonic extraction, destructive analysis of some certified rock samples employing ultrasonic waves was applied to two elements, Na ...
Investigation of separation and indentification possibilities of some metal-dithizonate complexes by sequential TLC-IR system
(2005)
The separation and identification possibilities of a number of metal-dithizonate complexes were investigated by means of a TLC-IR sequential system. Dithizonate complexes of some metal cations were pre-pared in a predetermined ...
Removal of Cu(II), Zn(II) and Co(II) ions from aqueous solutions by adsorption onto natural bentonite
(2007)
In this study, the removal of Cu(II), Zn(II) and Co(II) ions from aqueous solutions using the adsorption process onto natural bentonite has been investigated as a function of initial metal concentration, pH and temperature. ...
Photocatalytic degradation of a textile azo dye, Sirius Gelb GC on TiO 2 or Ag-TiO 2 particles in the absence and presence of UV irradiation: The effects of some inorganic anions on the photocatalysis
(2004)
The aqueous phase photocatalytic degradation of Sirius Gelb GC used in the textile industry, was investigated. In order to optimize the working pH, three different dye solutions were prepared at pH 3.5; 7.0 and 11.0. One ...
Investigation of separation and identification possibilities of some metal-DEDTC complexes by sequential TLC-IR system
(Preston Publications, 2005)
The separation and identification possibilities of some metal-diethyldithiocarbamate (DEDTC) complexes are investigated by thin-layer chromatography-IR sequential system. DEDTC complexes of metal cations are prepared in a ...
Removal of some heavy metal cations from aqueous solution by adsorption onto natural kaolin
(2005)
The adsorption removal of some heavy metal cations such as Cu(II), Zn(II) and Co(II) from aqueous solution onto kaolin has been studied using the batch method with initial metal ion concentrations within the range 15-70 ...
