Perfluorooctanoic acid (PFOA) has become a global concern due to its toxicity and persistent nature. It has been detected in water environments in recent years. Therefore, removal techniques are essential for minimizing human health risks and environmental impacts. The main objective of this study is to investigate the efficiency of adsorbents in the removal of batch and column PFOA. Batch adsorption experiments were conducted to study four adsorbents (PFA300, Dow Marathon A, XAD4, and GAC). The equilibrium adsorption data fitted well to the Freundlich isotherm for all adsorbents. PFA300 exhibited the maximum adsorption capacity (Freundlich K_f value = 117). The continued removal of PFOA was conducted by column. PFA300 exhibited the best performance over the longest duration of operation. The Yoon–Nelson model was employed to predict the half-saturation times of all adsorbents. The adsorbents were tested for regeneration. PFA300 and XAD4 yielded high regeneration percentages. Based on the results, PFA300 was the most effective material for removing PFOA in water and wastewater because it exhibited the highest adsorption capacity, the longest duration of operation, and the highest PFOA recovery percentage.
