Chelidamic Acid as a New Eluent for the Determination of Fe(II) and Fe(III) Species and Other Metals by High Performance Chelation Ion Chromatography
(Springer HeidelbergHeidelbergAlemanha, 2012)
Cloud-point extraction/preconcentration on-line flow injection method for mercury determination
(Elsevier Science, 2004-01)
A cloud-point extraction/preconcentration (CPE/P) step is incorporated on-line into a flow injection system which is used to determine low levels of Hg(II) added to natural water samples. The analyte is complexed with ...
Advances in estimatión and control for flotatión columns
(2010)
Flotation is multivariable process exhibiting uncertain and nonlinear dynamics as well as being perturbed by unmeasured disturbances. Optimization of this process is therefore a complex undertaking. Although real-time ...

General solution for shear strength estimate of RC elements based on panel response
(Elsevier Ltd, 2018)
The capacity of structural systems subjected to shear loads commonly distinguished by discontinuities such as point loads or supports, or abrupt changes of cross section, where complex fields of stresses and strains are ...
Simultaneous and highly sensitive determination of selenium and tellurium species in environmental samples by on-line ionic liquid based in-situ solvent formation microextraction with hydride generation atomic fluorescence spectrometry detection
(Elsevier Science, 2021-01)
A novel on-line preconcentration and speciation analysis method for the simultaneous determination of inorganic Se and Te species is presented in this work. The methodology is based on the on-line formation of a hydrophobic ...
A two-stage procedure for efficiently solving the integrated problem of production, inventory, and distribution of industrial products
(Elsevier, 2020-03-04)
This paper deals with the problem of optimally planning the production, inventory and distribution of products transported via multi-compartment vehicles. It assumes that facilities in the distribution network have ...
A novel on-line preconcentration method for trace molybdenum determination by USN-ICP OES with biosorption on immobilized yeasts
(Elsevier Science, 2007-08)
A new system for on-line preconcentration of molybdenum by sorption on a minicolumn associated to inductively coupled plasma - optical emission spectrometry with ultrasonic nebulization was studied. It is based on the ...
