提出了一种简便的TPD谱图处理法——等脱附速率法。此法与查表法相结合,有助于确定脱附反应动力学级数。实验证明,该法适用于从一级或二级脱附反应TPD谱求解脱附活化能E_d和指前因子k_o值。
A simple TPD spectrum processing method - equal desorption rate method was proposed. This method, combined with the look-up method, helps determine the desorption kinetic series. Experiments show that the method is suitable for solving the desorption activation energy E_d and the pre-exponential factor k_o from the primary or secondary desorption TPD spectra.
