Caracterização de escamas do peixe piau (Leporinus elongatus) e sua aplicação na remoção de Cu(II) de meio aquoso

Abstract: Recebido em 4/3/08; aceito em 29/7/08; publicado na web em 20/1/09 CHARACTERIZATION OF THE PIAU FISH (Leporinus elongatus) SCALES AND THEIR APPLICATION TO REMOVE Cu(II) FROM AQUEOUS SOLUTIONS. Characterization of fish scales of Leporinus elongatus and their application in the removal of Cu(II) from aqueous solutions are described. It was observed that the scales are mainly formed by hydroxyapatite and type I collagen. Adsorption of Cu(II) was performed using batch experiments at 25 0C. The ANOVA statistical re… Show more

“…The carbon, hydrogen, and nitrogen contents of 100FS were slightly higher than those reported by Santos et al [54] and Silva et al [13], who obtained around 20.0% carbon, 3.0% hydrogen, and 6.0% nitrogen. The oxygen content was lower than that informed by Silva et al [13], who identified values in the 70.0% range.…”

“…Taking into account the origin of this material, we can infer that the greater part of the humeral portion is formed by collagen, which appears in the spectrum as functional groups of amides I, II, and III. 21 The closest assignments of these groups related to each vibrational mode are listed in Table II. Visual inspection of the spectra did not reveal obvious visible differences between them.…”

“…As escamas correspondem de 2 à 4% do resíduo seco (GHALY et al, 2013). Na atividade pesqueira, as escamas de peixe geralmente são descartadas no lixo (SANTOS et al, 2009) ou jogadas no mar (GHALY et al, 2013).…”
