Simulação numérica e ensaios experimentais da remoção de Fe (III) da água para utilização nas indústrias alimentícias

Abstract: RESUMO ABSTRACTIn this study were performed the kinetics and isotherms of adsorption of the ions Fe (III) from synthetic affluent using activated carbon from coconut shell as adsorbent. The objective was to obtain the equilibrium and kinetic parameters of the process and thereby simulating different operating conditions in a adsorption column fixed bed. It was evaluated the influence of three temperatures different on the adsorption of Fe (III), in which the temperature increase indicated adsorption exotherm.T… Show more

“…Furthermore, it was possible to observe that the value of I was not null, indicating that the boundary layer is representative in the exchange process, as the value of this deviation indicates an approximation of the boundary layer in meq.g -1 and thus, the higher this value, the greater its importance to the process. The first stage that obtained a value of R 2 = 0.9099, confirmed that the exchange process is also governed by ion diffusion on the outer surface of the solid (Silva et al, 2015).…”

“…Sob esse contexto, o presente trabalho teve como objetivo a obtenção dos dados cinéticos e de equilíbrio termodinâmico em reator batelada e em coluna de leito fixo, e por meio de um algoritmo computacional e de sua validação, realizar uma análise de sensibilidade paramétrica das condições operacionais (SILVA et al, 2015). Por meio dos dados cinéticos, pode-se estimar as condições operacionais do leito, como: o efeito da vazão de entrada na coluna, altura e…”
