Abstract The simultaneous scrubbing of NO and SO2 can be finished with the Co(NH3)62+ ammonia solution. Activated carbon aids the regeneration of Co(NH3)62+ to retain the ability of absorbing NO. Acetic acid is tried to improve the catalytic capability of activated carbon. The best treatment condition is the carbon samples impregnated in 2.0 mol l−1 HAc solution for 20 h followed by being calcined at 600 °C for 4 h. The HAc modification increases surface area and acidic groups on the carbon surface. The experiments prove that the modified carbon can obtain a higher NO removal efficiency than the original carbon.

醋酸处理活性炭催化六氨合钴(II)溶液去除NO

摘要 用Co(NH3)62+氨溶液可以完成NO和SO2的同时洗涤。活性炭有助于 Co(NH3)62+ 的再生，以保持吸收 NO 的能力。醋酸试图提高活性炭的催化能力。最佳处理条件是碳样品在 2.0 mol l-1 HAc 溶液中浸渍 20 小时，然后在 600 °C 下煅烧 4 小时。HAc 改性增加了碳表面的表面积和酸性基团。实验证明，改性炭可以获得比原炭更高的NO去除效率。
