RESUMO

This paper presents the study of biotechnology processes for the removal of pHenol from aqueous solution in batch reactor in 3 separate cases (A), (B) and (C) respectively. As they adsorption of pHenols from aqueous solutions on chitosan, enzymatic degradation of pHenols by tyrosinase in aqueous solution and adsorption / degradation of pHenols in aqueous solutions containing chitosan immobilized tyrosinase. For this we examined the influence of varying temperature, pH, concentration of chitosan and stirring speed of the process (A), temperature, pH, concentration of free tyrosinase and stirring speed of the process (B) and Case (C), temperature , pH, concentration of chitosan, concentration of tyrosinase immobilized and speed of agitation.

ASSUNTO(S)
