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 removal of the contaminant in aqueous medium. Ecotoxicity test with Artemia salina showed that the degradation products are not toxic to this microcrustacean.Keywords: Sawdust biochar; adsorption; propranolol; advanced oxidative processes; emerging pollutant. ResumoO presente trabalho avaliou a eficiência do processo de adsorção usando biocarvão de serragem associado a Processos Oxidativos Avançados na remoção do fármaco propranolol em efluentes aquosos simulados. O biocarvão foi ativado quimicamente (lavado com HCl) e fisicamente (aquecimento à 800 °C) para favorecer a adsorção. Os resultados sugeriram que o equilíbrio de adsorção seguiu o modelo de monocamadas de Lagmuir. A combinação dos processos de adsorção e degradação resultou na remoção quase completa do contaminante em meio aquoso. Teste de ecotoxicidade com Artemia salina mostrou que os produtos de degradação não são tóxicos a este microcrustáceo.Palavras-chave: Biocarvão de serragem; adsorção; propranolol; processos oxidativos avançados; contaminante emergente.
