Abstract: A new method for the determination of kinetic parameter of catalytic reaction by near field laserthermal lens spectrometry is proposed in this paper.The parameters of the kinetic reaction in which traceiridium catalyzed oxidation of nile blue Aby potassium periodate in a weak acidic medium is determinatedsuccessfully by near field laser thermal lens spectrometry.The catalytic reaction is first-order in Ir(Ⅳ),nile blue Aand KIO4, and the apparent activation energy of the catalytic reaction is 70.9 kJ/mol.

Key words: Thermal lens spectrometry, Catalytic reaction, Kinetic parameter
