Multielement adsorption of metal ions using Tururi fibers (Manicaria Saccifera): experiments, mathematical modeling and numerical simulation

Abstract

2015): Multielement adsorption of metal ions using Tururi fibers (Manicaria Saccifera): experiments, mathematical modeling and numerical simulation, Desalination and Water Treatment, A B S T R A C TA numerical and experimental study of the multielement adsorption of Cd 2+ , Cu 2+ , Ni 2+ , and Pb 2+ metal ions in batch and column system were carried out in aqueous solution using Tururi fibers as adsorbent. The kinetics and thermodynamic equilibrium parameters were studied. The adsorption kinetics was fitted to the homogeneous diffusion model and the results showed good linear correlation coefficients. Furthermore, a mathematical model was built to describe the mass transfer kinetics for fixed bed column tests. The effects of constant adsorption equilibrium, external mass transfer, and intraparticle diffusion resistance on breakthrough curves were studied. The equations which describe the phenomenology were discretized using the finite volumes method with the weight upstream differencing scheme and central difference scheme formulations. The results for the breakthrough curves obtained through simulation showed good agreement compared with the experimental data.

Amazon Natural Fibers for Application in Engineering Composites and Sustainable Actions: A Review

“…It is important to highlight that there are several plants in the Amazon region whose fibers were not addressed in this study but also have promising applications in engineering composites. Some examples of these fibers include ouricuri [299], embira [300], taboa [301], titica vine [302,303], tururi [304][305][306], inajá [307], ubuçu [308,309], jarina [310], and patauá [311,312], among others. These fibers have significant potential for use in various industrial applications, replacing synthetic reinforcements with natural materials and promoting sustainability.…”

Sociobiodiversidade e conservação na Amazônia: o caso da feira livre de Abaetetuba, Pará, Brasil

“…L.P. Queiroz) e o buçu (Manicaria saccifera Gaertn.). O pau-de-verônica (Dalbergia monetaria L. f.) é uma espécie de Fabaceae que ocorre naturalmente em estados da região norte e nordeste amplamente reconhecido por sua função na medicina tradicional (Melo et al, 2016). Estudo com esta espécie ocorre tanto em ambientes urbanos (Leão, Ferreira e Jardim, 2007), comunidades ribeirinhas (Gois, Lucas, Costa, Moura e Lobato, 2016) quanto em feiras livres (Bitencourt, Lima e Barros, 2014).…”

Optimization of Pb (II) Ion Removal from Synthetic Wastewater Using Dead (Chlorophyta) Macroalgae: Prediction by RSM Method

“…These biological materials mostly consist of cellulose and hemicellulose, but they also contain smaller amounts of organic and inorganic chemicals. Algae are regarded as efficient biosorbents due to their abundance of functional groups that can easily interact with particular pollutants in water, such as heavy metals [15]. Macroalgae have significant advantages over other biosorbents since they are abundant, can be grown in freshwater and saltwater under a variety of climatic settings, are inexpensive to prepare as a biosorbent and have a high heavy metal removal efficiency [16,17].…”
