Journal ArticleDOI
Fluorescence fingerprint of fulvic and humic acids from varied origins as viewed by single-scan and excitation/emission matrix techniques
TL;DR: It is shown in this study that with selected lambda(ex), lambda(em) and (delta)(lambda) values, regular emission, excitation and synchronous spectra can, together, provide a good picture of the OM sources and aging for extracted HS.
Journal ArticleDOI
Green synthesis of zinc oxide nanoparticles: a review of the synthesis methodology and mechanism of formation.
Marina Bandeira,Marina Bandeira,Marcelo Giovanela,Mariana Roesch-Ely,Declan M. Devine,Janaina da Silva Crespo +5 more
TL;DR: A review of green synthesis of zinc oxide nanoparticles can be found in this article, where a summary of the different sources of biological substrates and methodologies applied to green synthesis is presented.
Journal ArticleDOI
Removal of diclofenac sodium from aqueous solution by Isabel grape bagasse
M. Antunes,Valdemar I. Esteves,Régis Guégan,Janaina da Silva Crespo,Andreia Fernandes,Marcelo Giovanela +5 more
TL;DR: In this article, the authors evaluated the morphologic and chemical characteristics of Isabel grape (Vitis labrusca ǫ× Vitis vinifera ) bagasse and described the adsorption of diclofenac sodium (DCF) from aqueous solutions by this biomass.
Journal ArticleDOI
Adsorption of diclofenac onto organoclays: Effects of surfactant and environmental (pH and temperature) conditions
Tiago De Oliveira,Régis Guégan,Thomas Thiebault,Claude Le Milbeau,Fabrice Muller,Vinicius Teixeira,Marcelo Giovanela,Mohammed Boussafir +7 more
TL;DR: The thermodynamic parameters derived from the fitting procedure point out the strong electrostatic interaction with organic cations adsorbed within the interlayer space in the organoclays for the adsorption of diclofenac.
Journal ArticleDOI
Removal of methyl violet 2B dye from aqueous solution using a magnetic composite as an adsorbent
L. R. Bonetto,F. Ferrarini,C. de Marco,Janaina da Silva Crespo,Régis Guégan,Marcelo Giovanela +5 more
TL;DR: In this paper, a halloysite-magnetite-based composite was used for the removal of methyl violet 2Bcationic dye, and the adsorption capacity of the composite was evaluated in a temperature-controlled batch system.
