Adsorption by Active and Inactive : Batch Studies
In this study, the optimal conditions for decolourizing Levafix brilliant blue EB (LB) were determined for both active (actively growing or active) and inactive (inactivated or inactive) Aspergillus oryzae . The adsorption capacity of active and inactive A. oryzae was compared using adsorption isoth...
