Optimization of the preconcentration system of cadmium with 1(2-thiazolylazo)-p-cresol using a knotted reactor and flame atomic absorption spectrometric detection
(Elsevier Science, 2004-08)
The present paper proposes an on-line preconcentration procedure for cadmium determination in drinking water samples. It is based on the precipitation of cadmium(II) ions on a knotted reactor (KR) using 1(2-thiazolylazo)-p-cresol ...
Ionic medium effects on equilibrium constants .1. Proton, copper(II), cadmium(II), lead(II) and acetate activity coefficients in aqueous solution
(Elsevier B.V., 1996-10-01)
The molar single ion activity coefficients associated with hydrogen, copper(II), cadmium(II) and lead(II) ions were determined at 25 degrees C and ionic strengths between 0.100 and 3.00 M (NaClO4), whereas for acetate the ...
Vibrational spectra of Cd2As2O7
(John Wiley & Sons Ltd, 2004-02)
The infrared and Raman spectra of Cd2As2O7, belonging to the thortveitite structural type, were recorded and are discussed on the basis of a factor group analysis and by comparisons with related compounds.
On Site Stripping Voltammetric Determination of Zn(II), Cd(II) and Pb(II) in Water Samples of the Cananeia-Iguape Estuarine-Lagoon Complex in Sao Paulo State, Brazil
(SOC BRASILEIRA QUIMICASAO PAULO, 2012)
Estuarine systems play an important role in the retention of toxic trace elements owing to the affinity of these elements with particles dissolved in water. This work presents the use of a voltammetric sensor to monitor ...
Synthesis of high-surface-area gamma-Al2O3 from aluminum scrap and its use for the adsorption of metals: Pb(II), Cd(II) and Zn(II)
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Several types of alumina were synthesized from sodium aluminate (NaAlO2) by precipitation with sulfuric acid (H2SO4) and subsequently calcination at 500 degrees C to obtain gamma-Al2O3. The precursor aluminate was derived ...

Aroilbis(N,N-dietiltioureatos) de cádmio (II) e chumbo (II): síntese e caracterização
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2014-07-18)
This work introduces the synthesis of two novel ligands belonging to the aroylbis(thiourea) class to study the spacer group influence in the complexes structure. Five membered rings were utilized as spacer groups such as ...
