文摘

The effective removal of aniline and its derivatives from wastewater is very important due to the high toxicity. Adsorption with a high-performance adsorbent is an efficient pathway. A novel activated carbon, ACUF-700, was synthesized using homemade ureaformaldehyde resin as the major carbon source carbonized at 700 °C. ACUF-700 is characterized by surface area analyzer, FTIR, elemental analyzer, and SEM. The adsorption properties of ACUF-700 towards anilines are also investigated by using batch methods. The test results showed that the ACUF-700 possesses higher specific surface area and narrower pore size distribution. In virtue of its developed pore structure and nitrogencontaining chemical groups, the adsorption capacities towards aniline, p-toluidine and p-chloroaniline could reach 95.6, 108.1 and 128.9mg/g, respectively. The adsorption process could be well described by the intra-particle mass transfer diffusion model and Sips model. Besides, ACUF700 was regenerated easily using diluted hydrochloric acid solution as eluent and ACUF700 possesses better reusability.
