一些元素在钨丝探针上的等温原子化机理

MECHANISM OF ATOMIZATION AT CONSTANT TEMPERATURE FOR SOME ELEMENTS IN A TUNGSTEN PROBE ATOMIZER

提出了一种理论模型以计算原子化的动力学级数和活化能。结果表明,实验元素在钨丝探针上的等温原子化均为零级动力学过程。根据活化能值讨论了可能的原子化途径。

A theoretical model has been proposed to calculate the kinetic order and the activation energy for atomization. The results show that the atomization of experimental elements at constant temperature in a tungsten probe atomizer is zero-order kinetic process. The activation energy has been used to elucidate atomization mechanism by correlation of the experimental energy values with the literature values.
