本文用1/100异三十碳烷对碳分子筛(TDX-01)进行改性,并结合采用小直径色谱柱,使柱效率大大提高,一氧化碳与二氧化碳得到了较好分离,在镍催化剂存在下,于360℃使一氧化碳和二氧化碳转化为甲烷,然后用氢火焰离子化检测器检出。方法的最小检出量<1ppm。可以满足聚合工艺的要求。本方法也可用于空气及其它永久性气体中微量一氧化碳和二氧化碳的测定。
In this paper, the molecular sieve (TDX-01) was modified by 1/100 isoprenoid in combination with the use of a small diameter column, so that the efficiency of the column was greatly improved and the carbon monoxide and carbon dioxide were well separated. In the presence of a nickel catalyst , Carbon monoxide and carbon dioxide were converted to methane at 360 ° C and then detected by a hydrogen flame ionization detector. The minimum detectable amount of the method is <1ppm. Polymerization process to meet the requirements. This method can also be used for the determination of trace amounts of carbon monoxide and carbon dioxide in air and other permanent gases.
