A Novel Electrochemical Enhancement of Activated Carbon Fibre for the Purification of Contaminated Pharmaceutical Effluents
Adsorption by activated carbon is conventionally used for wastewater treatment but is inefficient for pharmaceutical wastewater purification. This study investigates a novel, low-cost electrochemical enhancement of activated carbon fibre (ACF). With 1.0V applied, ACF’s effectiveness in removing acetone, a common pollutant in pharmaceutical waste, was increased by 107%. Over three cycles of adsorption and regeneration, the original effectiveness of unenhanced ACF plunged by 39.2%, while that of electrochemically enhanced ACF remained over 90%, demonstrating its increased reusability. A self-constructed prototype integrated electro-sorption and regeneration into one central chamber, allowing wastewater to be continuously purified as part of a cyclic process.
