Evaluation of the mass transfer phenomena in microchannel is an important parameter to estimate the chemical reaction in a micro reactor. In this study, the local mass transfer characteristics in the micro-channel is evaluated by using chemiluminescence(CL) of luminol reaction. Copper plate, which is the catalyst of the luminol reaction, was placed in the glass tube with a inner diameter of 4 mm. The copper ions eluted from the copper plate, then, the chemiluminescence layer was formed on the copper plate. The chemiluminescence layer was observed by digital camera with the microscope. The local mass transfer coefficient can be estimated by the local chemical reaction rate from the chemiluminescence layer profiles. This paper is a first step of the experimental study to measure the mass transfer coefficient using the chemiluminescence reaction.
