Application of mesoporous SBA-15 silica functionalized with 4-amino-2-mercaptopyrimidine for the adsorption of Cu(II), Zn(II), Cd(II), Ni(II), and Pb(II) from water
(Acta Chimica Slovenica, 2015-01-01) [Artigo]
This work reports the sol-gel synthesis of an SBA-15 silica and its functionalization with 4-amino-2-mercaptopyrimidine to perform adsorption of metal species from aqueous media. The functionalization of the material was ...
Characterization of corn (Zea mays) leaf powder and Its adsorption properties regarding Cu(II) and Cd(II) from aqueous samples
(Bioresources, 2015-01-01) [Resenha]
In this study, a green adsorbent made of corn leaf powder was applied in the removal of Cu(II) and Cd(II) from water samples. The material was characterized by Fourier transform infrared (FTIR) spectroscopy, which indicated ...
Cassava root husks as a sorbent material for the uptake and pre-concentration of cadmium(II) from aqueous media
(Orbital: the Electronic Journal of Chemistry, 2013) [Artigo]
Cassava husks were undergone to simple processes to obtain a fine powder whose particle diameter varied from 63 μm to 75 μm. The characterization of the material indicated the presence of the groups alcohol, amine and ...
Multilayer adsorption of Cu(II) and Cd(II) over Brazilian Orchid Tree (Pata-de-vaca) and its adsorptive properties
(Applied Surface Science, 2015-08-01) [Artigo]
Through very simple and inexpensive processes, pata-de-vaca leaves were turned into a powder and applied as an adsorbent for the uptake of Cu(II) and Cd(II) from water. The material was characterized through SEM, EDX, FTIR ...
