Abstract:

氨气是一种无色而具有强烈刺激性气味的碱性气体,不仅对人和动物健康造成危害,还会对空气造成污染.腐殖土有疏松多孔的结构和羧基、羟基等官能团.实验以腐殖土为原料,采用典型的酸、碱、盐对其进行改性,以扩大比表面积和孔径,来改善腐殖土对氨气的吸附能力.结果表明:用17%的H2SO4溶液,液固比为8∶1,60℃活化8h,105℃下烘干的条件下改性得到的腐殖土比表面积最大,由原样的12 m2·g-1提高到46 m2·g-1,提高3.83倍.改性后的腐殖土中加入1%的甲基纤维素,制成的吸附剂在200℃焙烧2h,穿透时间由原样的10 min增长到90 min,提高了8倍.穿透吸附量由原样的0.085 mg· g-1增加到2.3 mg·g-1,提高了26倍.
