In this study, phenol-based activated carbons (ACs) were fluorinated at various fluorine partial pressures (0.01∼0.03 MPa) and the Cr 6+ ion adsorption of fluorinated ACs was investigated. According to BET and XPS results, the specific surface area and total pore volume of fluorinated ACs increased by 24.7 and 55.8%, respectively, and fluorine functional groups were introduced to AC surface. The most optimized condition of Cr
