The Determination of Dynamic Adsorption Curve, Adsorption Capacity and Breakthrough Capacity of Powdered Activated Carbon for Perfluorooctanoic Acid elimination from Water

摘要

The batch and dynamic adsorption of powdered activated carbon (PAC) as an adsorbent to eliminate the PFOA from the water for reuse has been studied. The first 100 mL influent (0.5mmol/L) was totally adsorbed (100%) and more than eighty percent adsorption of PFOA was observed in the next 101-230mL influent. The static adsorption capacity and the breakthrough capacity were 104.6mg/g and 95.22mg/g respectively. The results obtained in the study helped in developing a new process in the water reuse system to eliminate PFOA from water and also established the technical foundation for the practical application of adsorption process.
