| Abstract | AbstractAs an oxidation intermediate generated in advanced oxidation processes, 1,4-benzoquinone, a toxic intermediate has drawn increasing attentions due to its high toxicity. Activated carbon fibre (ACF) was calcined and employed for the efficient removal of 1,4-benzoquinone by adsorption. Although no noticeable change was observed on the surface morphologies of the ACF after calcination at 300°C, the results showed that the adsorptive removal efficiency of the thermally treated ACF was enhanced by 25.1% compared to the raw ACF. Energy dispersive X-ray analysis indicated that the oxygen content of the thermally treated ACF increased significantly, which might contributed to its higher adsorption capacity. Langmuir isotherm and pseudo-second-order model well fitted the experimental data. Maximal adsorption capacity of 315.2 mg/g was achieved at neutral pH and 25°C. Both neutral and acidic conditions were favorable for the 1,4-benzoquinone adsorption on the calcined ACF. The ionic strength effect experime... |
