Journal ArticleDOI
Development of a chitin/graphene oxide hybrid composite for the removal of pollutant dyes: Adsorption and desorption study
Joaquín Antonio González,María Emilia Villanueva,Lidia Leonor Piehl,Guillermo Javier Copello +3 more
TL;DR: In this article, the synthesis of chitin and graphene oxide (Chi:nGO) hybrid gels in mild conditions and their use as biosorbents in solid-liquid batch systems was presented.
Journal ArticleDOI
Removal of dyes from water using chitosan hydrogel/SiO2 and chitin hydrogel/SiO2 hybrid materials obtained by the sol-gel method.
Guillermo Javier Copello,Guillermo Javier Copello,Andrea Mathilde Mebert,Mariana Raineri,Mariela P. Pesenti,Luis E. Diaz,Luis E. Diaz +6 more
TL;DR: The main mechanism of dye adsorption was found to be a spontaneous charge associated interaction, except for EB adsor adaptation on chitin/SiO(2) matrix, which showed to involve a lower energy physical adsorptive interaction.
Journal ArticleDOI
Antimicrobial Activity of Starch Hydrogel Incorporated with Copper Nanoparticles
María Emilia Villanueva,Ana Maria del Rosario Diez,Joaquín Antonio González,Claudio Javier Pérez,Manuel Tomás Orrego,Lidia Leonor Piehl,S. Teves,Guillermo Javier Copello +7 more
TL;DR: It is believed that the designed Si-Cu NP loaded hydrogel may show high potential for applications in various clinical fields, such as wound dressings and fillers.
Journal ArticleDOI
Immobilized chitosan as biosorbent for the removal of Cd(II), Cr(III) and Cr(VI) from aqueous solutions.
TL;DR: The generation of layer-by-layer silicate-chitosan composite biosorbent demonstrated chitOSan retention and had better sorption capacities than those without it and the use of a coated surface would facilitate sorbent removal from medium after adsorption.
Journal ArticleDOI
Chitin hydrogel reinforced with TiO2 nanoparticles as an arsenic sorbent
María Luz Peralta Ramos,Joaquín Antonio González,Sabrina G. Albornoz,Claudio Javier Pérez,María Emilia Villanueva,Sergio A. Giorgieri,Guillermo Javier Copello +6 more
TL;DR: In this paper, chitin hydrogels were reinforced with TiO 2 nanoparticles acting as fillers, and the mechanical and physicochemical characteristics of these hydrogel were studied by oscillatory rheology, infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Small Angle X-ray Spectroscopy(SAXS).
