Abstract: Three equations to calculate activation energy of desorption (Ed) were obtained from Polan-gi-Wagner model and TPD profile,Ed=Rln(N1/N2)nT1T2/ΔT and Ed=0.02T1T2/ΔT1/2 (n=1) or Ed=0.03T1T2/ΔT1/2 (n=2) Ed values can be calculated quickly from TPD peak width ΔT and its corresponding parameters by using the three equations. Comparating with other methods, the results are consistent with each other.
Key words: Peak width method, Quick determination, TPD activation energy
