The adsorption of anthracene by the activated carbon or P. oceanica was studied over a pH range of 2–12 at 25 ± 1 °C. Initial concentration of anthracene was 4 mg/L. The influence of the initial solution pH was studied by shaking, in different brown flasks, 0.3 g of sorbent and 30 mL of the anthracene solution (4 mg/L) at different pHs.
