羰基铁的电子吸收效能研究

Electron Capture Ability of Iron Pentacarbonyl: An Experimental Study

通过释放化学物质主动扰动电离层继而人工影响电波的传播效果,具有广阔的应用前景。本文运用阴极射线管(CRT)评价法和离子迁移谱(IMS)评价法对羰基铁的电子吸收效能进行了实验评价。CRT评价法表明,在低压1~4Pa条件下,羰基铁相对而言具有优越的电子吸收效能,特别是在1.9~2.7Pa的压力下,其电子吸收效能优于CO、CO2和SF6;IMS评价法表明,羰基铁表现出明显的电子吸收效能,且对电子的吸收效果随着进样量增加而增强,在相同的进样分子数时,相对于CO、CO2,羰基铁的电子吸收效能更优。此外,考虑到羰基铁相对较低的毒性,认为羰基铁是有潜力的、有广泛应用前景的电子扰动物质。

We experimentally addressed the subject of ionospheric disturbances by releasing chemicals.The influence of the pressure on the electron capture ability of chemicals,including Fe(CO)5,CO,CO2 and SF6,was investigated in cathode ray tube(CRT) and ion mobility spectrometry(IMS) methods.The results show that in 1~4 Pa pressure range,Fe(CO)5 exhibited excellent electron-capture ability.To be specific,as the flow-rate of Fe(CO)5 in the purging gas mixture increased,its e-capture ability significantly increased.When it comes to ionospheric electron disturbance with the same number of molecules,Fe(CO)5 outperforms CO and CO2,because of a stronger e-capture ability.In addition,Fe(CO)5 is much less toxic to humans than other metal carbony compounds such as Ni(CO)4.We suggest that Fe(CO)5 may be a promising ionospheric electron disturbance material.
