摘要
采用XRD、~1H MAs NMR、^(13)C MAs NMR和~1H NMR等方法研究不同状态下浸渍活性炭吸附剂的结构以及穿透后产物的存在状态。谱学表征分析和定量分析结果证明,碘甲烷与吸附剂之间发生化学反应,其形式为一个六次甲基四胺分子结合两个碘甲烷分子,产物为含两个碘离子的季铵盐。
The impregnated activated carbon adsorbents before and after breakthrough were studied by XRD,^1H MAS NMR,13C MAS NMR and ＇H NMR techniques. The results showed that impregnated activated carbon adsorbents reacted with iodomethane and the reaction mechanism was proposed as follows： one hexamethylene tetramine （HMTA） molecule combined with two iodomethane molecules to form the product of quaternary ammonium salt contained two iodine ions.
