Peat as a natural solid-phase for copper preconcentration and determination in a multicommuted flow system coupled to flame atomic absorption spectrometry
A. P. S. Gonzales,M. A. Firmino,Cassiana Seimi Nomura,Fábio R.P. Rocha,Pedro Vitoriano de Oliveira,Ivanise Gaubeur +5 more
TL;DR: The results obtained for copper determination in these samples agreed with those achieved by graphite furnace atomic absorption spectrometry (GFAAS) at the 95% confidence level.
Journal ArticleDOI
Multicommutation in flow analysis: concepts, applications and trends
Fábio R.P. Rocha,Boaventura F. Reis,Elias A.G. Zagatto,José L. F. C. Lima,Rui A. S. Lapa,João L.M. Santos +5 more
TL;DR: In this article, the concept of multicommutation is reviewed in order to permit a proper evaluation of the characteristics and potentialities of related flow systems, to assist methodological implementation and to discuss similarities with other existing strategies.
Journal ArticleDOI
Recent advances on determination of milk adulterants.
Carina F. Nascimento,Patrícia Menezes Santos,Edenir Rodrigues Pereira-Filho,Fábio R.P. Rocha +3 more
TL;DR: This review focuses on critical evaluation of analytical approaches for assay of milk adulteration, with emphasis on applications published after 2010 and alternatives for fast, environmentally friendly and in-situ detection of Milk adulterants.
Journal ArticleDOI
Green chemistry and the evolution of flow analysis. A review.
TL;DR: The evolution of flow analysis towards green analytical chemistry is demonstrated by comparing classical procedures implemented with different flow approaches, and the ability to implement processes unreliable in batch to replace toxic chemicals is emphasized.
Journal ArticleDOI
An improved flow system for phenols determination exploiting multicommutation and long pathlength spectrophotometry.
TL;DR: A greener and sensitive procedure for spectrophotometric determination of phenols based on a multicommuted flow system with a 100cm optical path flow cell that exploited the oxidative coupling of phenolic compounds with 4-aminoantipyrine in alkaline medium containing potassium hexacyanoferrate(III).
