| 摘 要： | 采用浸渍法制备了负载IB族元素的系列金属基海泡石,用气相色谱等手段对制得的金属基海泡石对NO的吸附性能进行研究,并且对灼烧温度、金属负载量、分散度和压力等影响因素进行了讨论。实验结果表明,经过酸改性、负载金属后的海泡石对NO的吸附能力比原矿有很大的提高;选择出Cu/海泡石的最佳灼烧温度为300℃,最佳Cu负载量为5％;并证明在实验条件下Cu/海泡石上的NO吸附符合经验吸附等温式。

| Abstract: | Sepiolite loaded with Cu, Ag and Au were prepared by impregnation. Their adsorption of NO was investigated by gas chromatography. The effects of the calcination temperature, the loading amount and dispersion of Cu and the pressure of NO on the adsorption ability of Cu/sepiolite were also studied. The results showed that the sepiolite loaded with metal had better adsorption ability than that hadn' t been impregnated. The Cu/sepiolite which had the best adsorption ability for NO was calcined at 3001 and the loading amount of Cu was 5% . The results fit the Fre-undlich equation well. |
