Method & Evidence

AimTo investigate the efficacy of enzyme-immobilized activated carbon from coconut shell for the removal of pharmaceutical pollutants from water.
MethodExperimental research
ProcedureLaccase enzyme was immobilized onto three types of granular activated carbon (GACs) derived from coconut shells. The adsorption and enzymatic degradation of four pharmaceutical compounds (diclofenac, amoxicillin, carbamazepine, and ciprofloxacin) were evaluated under varying conditions (pH, temperature, enzyme concentration). The performance of the immobilized enzyme system was compared to adsorption alone. Reusability of the immobilized enzyme was also tested.
