Sequential determination of nickel and cadmium in tobacco, molasses and refill solutions for e-cigarettes samples by molecular fluorescence
(Elsevier Science, 2017-11-03)
In this work, a new procedure was developed for separation and preconcentration of nickel(II) and cadmium(II) in several and varied tobacco samples. Tobacco samples were selected considering the main products consumed by ...
Preparation and thermal decomposition of copper(II), zinc(II) and cadmium(II) chelates with 8-hydroxyquinoline
(Sociedade Brasileira de Química, 1999-02-01)
When the compounds are heated in an inert atmosphere it can be verified the consecutive partial sublimation, fusion, partial volatilization and partial thermal decomposition of the anhydrous complexes. When in an oxidating ...

Application of Box–Behnken design in the optimisation of an on-line pre-concentration system using knotted reactor for cadmium determination by flame atomic absorption spectrometry
(2005)
The present paper proposes an on-line pre-concentration system for cadmium determination in drinking water using flame atomic absorption spectrometry (FAAS). Cadmium(II) ions are retained as 1-(2-pyridylazo)-2-naphthol ...
Structural and IR-spectroscopic characterization of cadmium and lead(II) acesulfamates
(Verlag der Zeitschrift für Naturforschung, 2017-10)
Cadmium and lead(II) acesulfamate, Cd(C4H4NO4S)2 2H2O and Pb(C4H4NO4S)2, were prepared by the reaction of acesulfamic acid and the respective metal carbonates in aqueous solution, and characterized by elemental analysis. ...
Structural study of a series of synthetic goethites obtained in aqueous solutions containing cadmium(II) ions
(J C P D S-int Centre Diffraction Data, 2003-03-01)
The capacity of goethite for Cd-II substitution has been explored in a series of synthetic samples prepared from Fe-III and Cd-II nitrate solutions aged 21 days in alkaline media. The total metal content ([ Fe] + [ Cd]) ...
Cassava root husks as a sorbent material for the uptake and pre-concentration of cadmium(II) from aqueous media
(2013)
Cassava husks were undergone to simple processes to obtain a fine powder whose particle diameter varied from 63 μm to 75 μm. The characterization of the material indicated the presence of the groups alcohol, amine and ...
