Estimativa da incerteza de medição associada a ensaio químico qualitativo de derrames de óleo por FTIR

Abstract

An alternative to remove potentially toxic metals such as Cd(II) and Pb(II) is biosorption can be performed using biomasses such as Bark Pequi ( Caryocar brasiliense Camb ), Sawdust W ood T eca (T ectona grandis) and the fungus Ear Pau ( Pycnoporus sanguineus ). This article aims to compare the potential of biomass biosorption Bark Pequi, Sawdust W ood T eak and fungus Ear Pau in mixed synthetic solutions of Cd(II) and Pb(II). The results showed that the biomass and possessed it good capacity retention rates of metal species under study . Meantime biomass that has owned better biosorption for ion Cd(II) was the Sawdust W ood T eca and ion Pb(II) biomass Bark Pequi. Keywords: biomass, potential to biosorption, toxic metals.
