Journal ArticleDOI
Adsorption of FD&C Red No. 40 by chitosan: isotherms analysis.
Jeferson Steffanello Piccin,Mery L. G. Vieira,Janaína Oliveira Gonçalves,Guilherme Luiz Dotto,Luiz Antonio de Almeida Pinto +4 more
TL;DR: In this article, the effects of pH (5.7, 6.6 and 7.5), particle size ranges (0.10−± 0.02, 0.18−±−0.02 and 0.26−±-0.2), deacetylation degree (42 −±−5, 64 −± −3% and 84 −±-3%) and temperature (25, 35 and 45 −°C) were investigated.
Journal ArticleDOI
Development of chitosan based hybrid hydrogels for dyes removal from aqueous binary system
Janaína Oliveira Gonçalves,J. P. Santos,Estéfani Cardillo Rios,Marselle Martins Crispim,Guilherme Luiz Dotto,Luiz Antonio de Almeida Pinto +5 more
TL;DR: In this paper, crosslinked hydrogel with glutaraldehyde (HyCG) was developed, characterized and applied for the adsorption of Food Blue 2 (FBL2) and Food Red 17 (FR17) from aqueous binary system.
Journal ArticleDOI
Synthesis of a bio–based polyurethane/chitosan composite foam using ricinoleic acid for the adsorption of Food Red 17 dye
Rejiane da Rosa Schio,Bruno C. da Rosa,Janaína Oliveira Gonçalves,Luiz Antonio de Almeida Pinto,Evandro S. Mallmann,Guilherme Luiz Dotto +5 more
TL;DR: The results showed that polyurethane foams are capable to support chitosan, generating an adsorbent with better mechanical characteristics and high potential to remove anionic dyes from aqueous media.
Journal ArticleDOI
Removal of fluoride from fertilizer industry effluent using carbon nanotubes stabilized in chitosan sponge
Lutiane N. Affonso,Jorge L. Marques,Valéria V.C. Lima,Janaína Oliveira Gonçalves,Sergiane Caldas Barbosa,Ednei Gilberto Primel,Thiago A. L. Burgo,Guilherme Luiz Dotto,Luiz Antonio de Almeida Pinto,Tito R.S. Cadaval +9 more
TL;DR: The adsorbent capacity was around 975.4 mg g-1, showing the potential of the hybrid material to remove fluoride from a real matrix, and the high adsorption capacity was attributed to the chitosan functional groups and thehigh interaction area promoted by sponge form and the carbon nanotube.
Journal ArticleDOI
Single and competitive dye adsorption onto chitosan-based hybrid hydrogels using artificial neural network modeling.
P.S. Pauletto,Janaína Oliveira Gonçalves,Luiz Antonio de Almeida Pinto,Guilherme Luiz Dotto,Nina P.G. Salau +4 more
TL;DR: A predictive artificial neural network (ANN) was implemented and proved to be effective in predicting dye adsorption capacity of each hydrogel, even for the competitive adsor adaptation, as the R values were close to unity for all simulation systems.
