Use of Biochar and Advanced Oxidative Processes for the Removal of Propranolol from Simulated Aqueous Effluents

Abstract: Abstract:The present work evaluated the efficiency of the adsorption process using sawdust biochar associated to Advanced Oxidative Processes in the removal of the drug propranolol in simulated aqueous effluents. The biochar was activated chemically (washed with HCl) and physically (heating at 800 ° C) to favor adsorption. The results suggested that the adsorption equilibrium followed the model of Lagmuir monolayers. The combination of the adsorption and degradation processes resulted in almost complete remova… Show more

“…The TG curves were obtained using a thermal analyzer (Shimadzu, TGA-50) (Quioto, Japan) using a heating rate of 10 • C min −1 between 25 and 800 • C in an inert nitrogen atmosphere. X-ray diffraction was performed using a Shimadzu instrument, model Labx-XDR 6000 (Quioto, Japan) [3,[27][28][29][30].…”

“…Outra vantagem destes processos é que estes podem ser utilizados no tratamento de contaminantes cuja concentração seja muito baixa, chegando até às concentrações de ppb. 11,14,15 Dentre os POA's, a reação de Fenton (equação 1), amplamente divulgada na literatura científica e conhecida pela sua simplicidade operacional e grande eficiência de degradação, pode tornar-se um método ainda mais eficiente com a utilização de radiação ultravioleta que é responsável pelo aumento da taxa de degradação do poluente orgânico, sendo conhecido como processo Foto-Fenton (equação 2). A redução de Fe 3+ a Fe 2+ é responsável pelo efeito positivo da radiação sobre a reação.…”
