将氨水、无水乙二胺用于活性炭改性,使用无水乙二胺改性后的再生性能较好,经过多次吸附与再生后仍能保持一定的稳定性,水分的存在不利于二硫化碳的脱除.FT-IR和TG表征也证实了经无水乙二胺改性后,活性炭的吸附量提高.采用抽真空和加热再生相结合的方法进行再生,一定温度条件下再生率可以达到85%.

In several modifying nitrogenous substances, the activated carbon which modified by anhydrous ethylenediamine had better regeneration property, and remained certain stability after several absorption and regeneration. The presence of water was not good for the removal of carbon disulfide. FT-IR and TG confirmed that the activated carbon adsorption capacity increased after anhydrous ethylenediamine modified. The regeneration rate could reach 85% under certain temperature conditions by combination of vacuum and heat.
