Kinetics, isotherm and thermodynamic studies of adsorption of Acid Blue 193 from aqueous solutions onto natural sepiolite
(Elsevier Science BV, 2006)
In the present study, natural sepiolite was used as an adsorbent for the investigation of the adsorption kinetics, isotherms and thermodynamic parameters of an acid dye (Acid Blue 193, AB 193) from aqueous solution at ...
Determination of paracetamol based on electropolymerized-molecularly imprinted polypyrrole modified pencil graphite electrode
(Elsevier Science Sa, 2007)
Preparation of a molecularly imprinted polymer (MIP) film and its recognition property for paracetamol are investigated. The polypyrrole (PPy) film was prepared by the cyclic voltammetric deposition of pyrrole (Py) in the ...
Synergistic Effect of Lithium Perchlorate and Sodium Hydroxide in the Preparation of Electrochemically Treated Pencil Graphite Electrodes for Selective and Sensitive Bisphenol A Detection in Water Samples
(Wiley-V C H Verlag GMBH, 2014)
In this study, pencil graphite electrodes were activated electrochemically in the presence of different supporting electrolytes and used for the selective and sensitive determination of bisphenol A (BPA) in water samples. ...
Synthesis and catalytic activity of perfluoroalkylated pyridine-palladium(II) complex toward olefin hydrogenation in scCO(2) and conventional organic solvents
(Elsevier Science BV, 2006)
The perfluoroalkylated pyridine, (o-COOCH2(CF2)7CF(3)-NC5H4), has been synthesized in two step from nicotinic acid and then the title compound, [Pd(o-COOCH2,-(CF2)(7)CF3-NC5H4)(2)(OAc)(2)], obtained by reaction with ...
Unusual Very Strong O-H center dot center dot center dot O Hydrogen Bonding in Zinc Complex: Crystal Structure and Photoluminescence of [Zn(HL)(bpy)(2)(H2O)](2)(L) (L = O2C(CF2)(6)CO2, bpy = 2,2 ' bipyridine)
(Springer/Plenum Publishers, 2012)
The centrosymmetric dimer zinc compound, [Zn(HL)(bpy)(2)(H2O)](2)(L), (L = O2C(CF2)(6)CO2, bpy = 2,2'-bipyridine), was obtained through the reaction of Zn(ClO4)(2)center dot 6H(2)O, bpy and perfluorosuberic acid. Zn(II) ...
Oxidation of 2,6-di-tert-butylphenol with tert-butyl hydroperoxide catalyzed by iron phthalocyanine tetrasulfonate in a methanol-water mixture
(Elsevier Science BV, 2007)
The oxidation of 2,6-di-tert-butylphenol (DTBP) with tert-butyl hydroperoxide (Bu'OOH) catalyzed by iron phthalocyanine tetrasulfonate ([FePcTS]) in a 8-to-1 methanol-water mixture resulted with about 70-80% conversion of ...
Phosphorus-nitrogen compounds: Synthesis and spectral investigations on new spiro-cyclic phosphazene derivatives
(Pergamon-Elsevier Science LTD, 2007)
The condensation reaction of {N-[(2-hydroxyphenylmethyl)amino]-4,6-dimethylpyridine} (2), which is a reduction product of 1, with trimer N3P3Cl6 affords partially a substituted spiro-cyclic phosphazene derivative (3). The ...
Solubility of an acid dye in supercritical carbon dioxide by ion-pairing with dodecyltrimethylammonium bromide
(Elsevier Science BV, 2006)
In this study, solubility of Acid Red 57 (AR57), which is an anionic dye, in supercritical CO2 was investigated using an ion-pairing with dodecyltrimethylammonium (DTMA) bromide. The measurements of AR57 and AR57-DTMA in ...
Adsorption of Acid Blue 193 from aqueous solutions onto BTMA-bentonite
(Elsevier Science BV, 2005)
