Abstract:
Perfluorooctanoic acid (PFOA) is one of the per and polyfluorinated substances (PFAS) with strong
chemical bonds and high inertness. PFOA has been considered an environmental pollutant that effects human
health through water and food contamination. Many approaches have been used to remove PFOA and
adsorption methods are the most effective techniques for treating PFOA. This study aims to compare the
efficiency of PFOA removal using commercial activated carbons (bituminous activated carbon and coconut
shell activated carbon) and activated carbon synthesized from dried hemp stem. The porous textures of
activated carbon were examined by N2-sorption measurements. Batch adsorption tests were used to determine
the adsorption isotherms and adsorption kinetic, in which the adsorptions were investigated using high-
performance liquid chromatography (HPLC). The results showed that the commercial activated carbons
derived from bituminous have higher PFOA removal (89.14% and 93.20%) than that synthesized from hemp
activated at 450 *C (HEMP450, 69.07%) and coconut shell activated carbon (14.27%). The adsorption
isotherms of HEMP450 and the commercial activated carbon derived from bituminous fit with Langmuir
model, suggesting the homogenous monolayer adsorption. However, the activated carbon derived from
coconut shell fits with the Temkin model assuming the indirect interaction of adsorbent and adsorbate. The kinetic adsorption followed the pseudo second order model for the chemisorption kinetic process.
