Biosorption of Pb(II) and Cd(II) ions by Agave sisalana (sisal fiber)
Walter Nei Lopes dos Santos,Dannuza D. Cavalcante,Erik Galvão Paranhos da Silva,Cesário Francisco das Virgens,Fabio de S. Dias +4 more
TL;DR: In this article, the use of Agave sisalana (sisal fiber) as an natural adsorbent for ions Pb(II) and Cd(II), was proposed.
Journal ArticleDOI
Slurry Sampling and HG AFS for the Determination of Total Arsenic in Rice Samples
Walter Nei Lopes dos Santos,Dannuza D. Cavalcante,Samuel Marques Macedo,Jéssica S. Nogueira,Erik Galvão Paranhos da Silva +4 more
TL;DR: In this article, a procedure for the determination of total arsenic in rice using slurry sampling and hydride generation atomic fluorescence spectrometry (HG AFS) was proposed.
Journal ArticleDOI
Mineral composition, nutritional properties, total phenolics and flavonoids compounds of the atemoya fruit (Annona squamosa L. x Annona cherimola Mill.) and evaluation using multivariate analysis techniques
Walter Nei Lopes dos Santos,Maria Celeste da Silva Sauthier,Dannuza D. Cavalcante,Clícia M.J. Benevides,Fabio de S. Dias,Daniele Cristina Muniz Batista dos Santos +5 more
TL;DR: The exploratory evaluation of 42 atemoya samples was performed through Principal Component Analysis (PCA), which discriminated green and ripe fruits according to their mineral composition, and the elements that contributed most for the variability between green and plum fruits were Ba, Ca, Cu, K, Mg and P.
Journal ArticleDOI
Multivariate optimization of a method for antimony determination by hydride generation atomic fluorescence spectrometry in hair samples of patients undergoing chemotherapy against Leishmaniasis
Manuelle Carvalho Cardozo,Dannuza D. Cavalcante,Daniel Levi França da Silva,Walter Nei Lopes dos Santos,Marcos A. Bezerra +4 more
TL;DR: Under the optimum experimental conditions, the method allows the determination of antimony in hair samples with detection and quantification limits of 1.4 and 4.6 ng g-1, respectively, and precision expressed as relative standard deviation (RSD) of 2.8%.
Journal ArticleDOI
Evaluation of optimal conditions for determination of low selenium content in shellfish samples collected at Todos os Santos Bay, Bahia, Brazil using HG-AFS.
Walter Nei Lopes dos Santos,Samuel Marques Macedo,Sofia Negreiros Teixeira da Rocha,Caio Niela Souza de Jesus,Dannuza D. Cavalcante,Vanessa Hatje +5 more
TL;DR: The developed method for the determination of total selenium content in shellfish after digestion of samples in block using cold finger system and detection using atomic fluorescent spectrometry coupled hydride generation (HG AFS) proved to be accurate, precise, cheap, fast, and could be used for monitoring Se inshellfish samples.
