DESENVOLVIMENTO DE EXPERIMENTO DIDÁTICO DE ELETROGRAVIMETRIA DE BAIXO CUSTO UTILIZANDO PRINCÍPIOS DA QUÍMICA VERDE
Autor: Guilherme Antonio Finazzi, Carlos Ney Martins, Milton Duffles Capelato, Luiz Henrique Ferreira
Publikováno v: Química Nova, Vol 39, Iss 1, Pp 112-117 (2016)
In this paper, we describe the development of low-cost teaching experiments of electrogravimetry for undergraduate students using principles of green chemistry. Copper was electrochemically deposited on brass under an electrical current density of 50

Potencialidades do dióxido de chumbo eletrodepositado como sensor potenciométrico Potentialities of electrodeposited lead dioxide as a potentiometric sensor
Autor: Milton Duffles Capelato, Neila Maria Cassiano
Publikováno v: Química Nova, Vol 21, Iss 4, Pp 493-498 (1998)
This paper proposes an experiment to be performed in both instrumental analysis and experimental physical-chemistry curricular disciplines in order to open options to develop challenging basic research activities. Thus the experimental procedures and

Oxidative decomposition of atrazine by a Fenton-like reaction in a H2O2/ferrihydrite system
Autor: Ladislau Martin-Neto, Milton Duffles Capelato, Juliana Cristina Barreiro, Hans Christian Bruun Hansen
Publikováno v: Water Research. 41:55-62
The oxidation of atrazine (ATZ) was studied in the presence of hydrogen peroxide (H(2)O(2)) and ferrihydrite at different concentrations and pHs. The rate of ATZ oxidation increased with H(2)O(2) concentration and is independent of pH ranging from 4

Utilização de um eletrodo de grafite recoberto com PbO2 incorporado em matriz de PVC como eletrodo indicador em titulações coulométricas
Autor: Milton Duffles Capelato, Luiz Antônio Ramos, N. M. Cassiano
Publikováno v: Eclética Química. 29:65-72
A aplicação de um eletrodo sensível a íons H3O+, obtido pelo recobrimento de um eletrodo de grafite com uma membrana polimérica contendo PbO2 incorporado em uma matriz de PVC (PbO2-PVC), como eletrodo indicador em titulações coulométricas de

Flow Injection Potentiometric Determination of Coke Acidity and Acetic Acid Content in Vinegar Using an Antimony Electrode
Autor: Milton Duffles Capelato, Romualdo Gama, Orlando Fatibello-Filho, Antonia Marli dos Santos
Publikováno v: Analytical Letters. 29:711-724
A flow injection potentiometric procedure is proposed for the determination of acidity of several samples using an antimony/ antimony oxide electrode. The ΔE/pH curve in phosphate buffer solutions in the pH range from 1.58 to 12.00 showed a linear s
