摘　　要：利用固定吸附床研究了不同金属离子改性的Y分子筛对一氧化氮的吸附性能。在所用的样品中,钴离子改性的Y分子筛显示出了最良好的吸附性能。钴离子改性的Y分子筛对一氧化氮吸附的穿透时间随着钴含量、浸渍液的pH值和粘合剂三氧化铝用量的变化而变化。另外,穿透时间还随吸附温度的升高而缩短。The adsorption capability of nitric oxide (NO) on various metal ion-containing Y-zeolite was examined by the adsorption measurements in a fixed bed flow adsorption apparatus. Among the samples used, the co-containing Y showed the greatest capability for breakthrough time and adsorption amount. The breakthrough time of NO on Co-containing was changed with Co-containing amounts、pH of load solution and Al2O3 amounts. Beside, with increasing adsorption temperature, the breakthrough time decreased.
