Biomonitoramento de Cr e Pb em peixes de água doce
Autor: Carolina Marília Martins Repula, Bruna Kauely de Campos, Edgard Moreira Ganzarolli, Mauro Chierici Lopes, Sueli Pércio Quináia
Publikováno v: Química Nova, Vol 35, Iss 5, Pp 905-909 (2012)
Trace metal content of three fish species harvested from a tank located in the City of Guarapuava-PR, Brazil were determined by digestion and voltametry. Trace metal content in fish samples were 0.10-1.30 µg/g (muscle) and 0.45-15.90 µg/g (liver) f

Determination of Aluminum Traces in Hemodialysis and Tap Water Using Standard Method's Procedure Modified and Flow Injection Ionic Exchange Preconcentration
Autor: Edgard Moreira Ganzarolli, Edson Luiz da Silva, Roldão R. U. de Queiróz
Publikováno v: Analytical Letters. 38:2089-2101
A procedure for the spectrophotometric determination of aluminum traces in water using a flow injection (FI) preconcentration system has been proposed. The flow system was made up of a peristaltic pump, an injector‐commutator, and a minicolumn fill

Use of NbO?SiO in an automated on-line preconcentration system for determination of copper and cadmium by FAAS
Autor: Edson Luiz da Silva, Eduardo Carasek, Edgard Moreira Ganzarolli
Publikováno v: Talanta. 62:727-733
A procedure for the determination of trace level of copper(II) and cadmium(II) by FAAS using an on-line preconcentration system has been proposed. In this system, copper and cadmium ions were adsorbed onto a minicolumn packed with silica gel modified

Feasibility of eliminating interferences in graphite furnace atomic absorption spectrometry using analyte transfer to the permanently modified graphite tube surface
Autor: Bernhard Welz, Adilson J. Curtius, Edgard Moreira Ganzarolli, Sandra M. Maia
Publikováno v: Spectrochimica Acta Part B: Atomic Spectroscopy. 57:473-484
A procedure is proposed to avoid spectral and/or non-spectral interferences in graphite furnace atomic absorption spectrometry (GF AAS) by transferring the analyte during the pyrolysis stage from a solid sampling platform to the graphite tube wall th

An automated on-line flow system for the pre-concentration and determination of lead by flame atomic absorption spectrometry
Autor: Valfredo Azevedo Lemos, Sergio Luis Costa Ferreira, Adilson J. Curtius, Ricardo Erthal Santelli, Edgard Moreira Ganzarolli
Publikováno v: Microchemical Journal. 68:41-46
The use of Amberlite XAD-2 modified by 2-(2-benzothiazolylazo)-2- p -cresol (BTAC) as a sorbent in an on-line pre-concentration system for lead determination has been proposed. The procedure is based on the sorption of lead(II) ions onto a minicolumn

Automated flow injection system for the preconcentration of bismuth and lead from acid solutions of alloys and determination by electrothermal atomic absorption spectrometry
Autor: Edgard Moreira Ganzarolli, Adilson J. Curtius, Maria Bertı́lia Oss Giacomelli
Publikováno v: Spectrochimica Acta Part B: Atomic Spectroscopy. 55:525-533
An automated flow injection system for the preconcentration of Bi and Pb from acid solutions of alloys is proposed. The system uses three-way solenoid valves, a peristaltic pump, a mixing coil and a minicolumn filled with activated carbon. The valves
