Journal ArticleDOI
Adsorption and desorption of Cu(II), Cd(II) and Pb(II) ions using chitosan crosslinked with epichlorohydrin-triphosphate as the adsorbent
TL;DR: In this study, chitosan was crosslinked with both epichlorohydrin (ECH) and triphosphate (TPP), by covalent and ionic crosslinking, respectively, and the resulting new CTS-ECH-TPP adsorbent was characterized by CHN analysis, EDS, FTIR spectroscopy, TGA and DSC, and it was demonstrated that the adsorption process proceeded according to the pseudo-second-order model.
Journal ArticleDOI
Hypoglycemic effect and antioxidant potential of kaempferol-3,7-O-(alpha)-dirhamnoside from Bauhinia forficata leaves.

TL;DR: Investigation of the effects of kaempferol-3,7-O-(alpha)-dirhamnoside (kaempferitrin), a major flavonoid compound of the n-butanol fraction from Bauhiniaforficata leaves, on serum glucose levels, as well as its antioxidant potential, found a significant hypoglycemic effect in normal and in alloxan-induced diabetic rats.
Journal ArticleDOI
Catecholase activity of a series of dicopper(II) complexes with variable Cu-OH(phenol) moieties.

TL;DR: The catecholase activity of a series of dicopper(II) complexes containing different numbers of phenol groups coordinated to the metal centers was studied to identify functional as well as structural models for the type III copper enzymes tyrosinase and catechl oxidase.
Journal ArticleDOI
Effect of surface and porosity of biochar on water holding capacity aiming indirectly at preservation of the Amazon biome.
Estela M.C. Cardoso Batista,Juliana Shultz,Tassya Thaiza da Silva Matos,Mayara Regina Fornari,Thuany M. Ferreira,Bruno Szpoganicz,Rilton Alves de Freitas,Antonio S. Mangrich,Antonio S. Mangrich +8 more
TL;DR: The results suggested that despite the effect of porosity on water retention, the zeta potential could be associated with the presence of negative charges by which hydrated cationic counterions were absorbed and retained.
Journal ArticleDOI
Metal binding by melanins: studies of colloidal dihydroxyindole-melanin, and its complexation by Cu(II) and Zn(II) ions.
TL;DR: Melanin solutions obtained from N-methylated DHI lack the pK(a) 6.3 buffer, consistent with its inability to form the quinone-imine tautomer, and the nature of the metal-binding sites are determined and the binding affinities are quantified.
