TL;DR: A preconcentrating/voltammetric multiwalled carbon nanotube modified glassy carbon electrode (MWCNT-GCE) has been developed for stripping analysis of carbendazim (Methyl Benzimidazol-2-yl Carbamate) based on dispersing MWCNT in water as mentioned in this paper.
Journal ArticleDOI
Flow-injection electrochemical determination of citric acid using a cobalt(II)-phthalocyanine modified carbon paste electrode.
Raphael Fonseca do Nascimento,Thiago Matheus Guimarães Selva,Thiago Matheus Guimarães Selva,Williame F. Ribeiro,Mônica F. Belian,Lúcio Angnes,Valberes B. Nascimento +6 more
TL;DR: The electrocatalytic activity of cobalt(II)-phthalocyanine immobilized in a carbon paste electrode for citric acid oxidation under a diffusion-controlled electrochemical process was employed to develop a selective flow injection amperomettric analysis method that compares advantageously to the all other citric Acid determination methods.
Journal ArticleDOI
Study of Electrochemical Oxidation and Quantification of the Pesticide Pirimicarb Using a Boron-Doped Diamond Electrode
Thiago Matheus Guimarães Selva,Thiago Matheus Guimarães Selva,William R. de Araujo,Raphael P. Bacil,Thiago R.L.C. Paixão +4 more
TL;DR: In this paper, an analytical method for carbamate pesticide pirimicarb quantification in water samples by differential pulse (DP) voltammetry is proposed, and an analytical curve was obtained from 2.0 to 219μmol L−1 with an estimated detection limit of 1.24μmol l−1.
Journal ArticleDOI
A coulometric flow cell for in-line generation of reagent, titrant or standard solutions
Severino Carlos B. Oliveira,Severino Carlos B. Oliveira,Elaine C.S. Coelho,Thiago Matheus Guimarães Selva,Francyana P. Santos,Mário César Ugulino de Araújo,Fabiane C. de Abreu,Valberes B. Nascimento +7 more
TL;DR: In this article, a universal and easily ON-OFF time operated coulometric flow cell for generation of chemicals is proposed, which can be used for generating reagents, titrants or standard solutions, and can be coupled to analytical equipments in combination with flow systems for generating micro-quantity amounts of chemicals in a wide concentration range.
Journal ArticleDOI
Automatic determination of chlorine without standard solutions using a biamperometric flow-batch analysis system.
Valberes B. Nascimento,Thiago Matheus Guimarães Selva,Elaine C.S. Coelho,Francyana P. Santos,Jadielson L.S. Antônio,José Radamés Ferreira da Silva,Edvaldo N. Gaião,Mário César Ugulino de Araújo +7 more
TL;DR: Low residue disposal and reagent consumption, allied with high accuracy and precision, make it very promising for routine applications, and the reliability of the proposed method is demonstrated.
