A new modeling strategy for third-order fast high-performance liquid chromatographic data with fluorescence detection: Quantitation of fluoroquinolones in water samples
(Springer Heidelberg, 2015-02)
Matrix augmentation is regularly employed in extended multivariate curve resolution-alternating least-squares (MCR-ALS), as applied to analytical calibration based on second- and third-order data. However, this highly ...
Fast chromatographic method for the determination of dyes in beverages by using high performance liquid chromatography-Diode array detection data and second order algorithms
(Elsevier Science, 2009-09)
A fast chromatographic methodology is presented for the analysis of three synthetic dyes in non-alcoholic beverages: amaranth (E123), sunset yellow FCF (E110) and tartrazine (E102). Seven soft drinks (purchased from a local ...
Modeling four and three-way fast high-performance liquid chromatography with fluorescence detection data for quantitation of fluoroquinolones in water samples
(Elsevier Science, 2014-01)
This paper presents a study regarding the acquisition and analytical utilization of four and three-way data, acquired by following the excitation?emission fluorescence matrices at different elution times, in a fast liquid ...
An integrated on-line method for the preconcentration and simultaneous determination of metsulfuron methyl and chlorsulfuron using oxidized carbon nanotubes and second order fluorescent data
(Elsevier Science, 2016-11)
Trace amounts of two sulfonylurea herbicides widely used for crops protection, metsulfuron methyl (MSM) and chlorsulfuron (CSF) were simultaneously determined taking into account the different kinetic photodegradation ...
Excitation-emission fluorescence-kinetic data obtained by Fenton degradation. Determination of heavy-polycyclic aromatic hydrocarbons by four-way parallel factor analysis
(Elsevier Science, 2017-04)
For the first time, a simple and environmentally friendly third-order/four-way calibration was applied for the simultaneous determination of five heavy-polycyclic aromatic hydrocarbons (PAHs) in interfering environments. ...
A second-order in time and space particle-based method to solve flow problems on arbitrary meshes
(Academic Press Inc Elsevier Science, 2019-03)
This work presents a novel proposal of a second-order accurate (in time and space) particle-based method for solving transport equations including incompressible flows problems within a mixed Lagrangian-Eulerian formulation. ...
Study of the Equilibrium, Kinetics, and Thermodynamics of Boron Removal from Waters with Commercial Magnesium Oxide
(Hindawi Limited, 2018)
In the present work, the equilibrium, thermodynamics, and kinetics of boron removal from aqueous solutions by the adsorption on commercial magnesium oxide powder were studied in a batch reactor. The adsorption efficiency ...
