~(204)Tl在几种金属和非金属表面上的释放行为研究

Tl作为类113号元素,测定了它在Ni,Pd,Mo,Ta,Zr,Ti,Au,Ag,Cu,Fe等金属表面上和SiO_2及石墨等非金属表面上的释放率和释放动力学,理论上计算了Tl在上述金属表面上的附吸焓并与实验结果进行了比较,讨论了两者之间存在差异的原因以及有关的影响因素。定性地预计了113号元素在上述表面上的释放行为和吸附焓。

INVESTIGATION OF THE RELEASE BEHAVIOUR OF ~(204)T1 FROM SOME METAL AND NON-METAL SURFACES

The release rate and release dynamics of thallium, which is used as the substitute for its ekaelement 113, are measured on the metal surfaces of Ni,Pd,Mo,Ta,Zr,Ti ,Au, Ag, Cu and Fe and non-metal surfaces of graphite and SiO2 The theoretical adsorption enthalpies of Tl on the metal surfaces mentioned above are calculated. The experimental and theoretical results are compared and the differences between them are discussed. The release behaviour and the adsorption enthalpies of element 113 on these surfaces are estimated qualitatively.
