Journal ArticleDOI
A flow injection procedure based on solenoid micro-pumps for spectrophotometric determination of free glycerol in biodiesel
Sidnei G. Silva,Fábio R.P. Rocha +1 more
TL;DR: The procedure was successfully applied to the analysis of biodiesel samples and the results agreed with the batch reference method at the 95% confidence level.
Journal ArticleDOI
Tungsten coil atomic emission spectrometry combined with dispersive liquid–liquid microextraction: A synergistic association for chromium determination in water samples
TL;DR: A novel and environment friendly analytical method is reported for total chromium determination and chromium speciation in water samples, whereby tungsten coil atomic emission spectrometry (WCAES) is combined with in situ ionic liquid formation dispersive liquid-liquid microextraction (in situ IL-DLLME).
Journal ArticleDOI
Electrochemically Reduced Graphene Oxide for Forensic Electrochemistry: Detection of Cocaine and its Adulterants Paracetamol, Caffeine and Levamisole
Diego P. Rocha,Rafael M. Dornellas,Edson Nossol,Eduardo M. Richter,Sidnei G. Silva,Mário H. P. Santana,Rodrigo A.A. Munoz +6 more
TL;DR: In this paper, the improved performance of electrochemically-reduced graphene oxide (ERGO) modified electrodes for the square-wave voltammetric detection of cocaine (COC) and its main adulterants paracetamol (PAR), caffeine (CAF) and levamisole (LEV).
Journal ArticleDOI
Sequential spectrofluorimetric determination of free and total glycerol in biodiesel in a multicommuted flow system
TL;DR: A new procedure based on the oxidation of glycerol by periodate, forming formaldehyde, which reacts with acetylacetone, producing the luminescent 3,5-diacetyl-1,4-dihydrolutidine is presented.
Journal ArticleDOI
Cloud point extraction to avoid interferences by structured background on nickel determination in plant materials by FAAS
TL;DR: An analytical procedure based on microwave-assisted digestion with diluted acid and a double cloud point extraction for nickel determination in plant materials by flame atomic absorption spectrometry successfully applied for sample clean up and the accuracy of the procedure was evaluated by nickel determinations in reference materials.
