Resolution of chemical reaction process with unknown kinetic model

Iterative target transformation factor analysis was applied to resolve the kinetic-spectral data matrix monitored in the process of spectroscopic reaction of unknown kinetic model and the kinetic spectrum of each component is obtained. A novel approach was proposed to estimate the initial vectors based on the spectral features such as the isoabsorptive point of the relative component in the system. With the proposed approach, the simulated data matrix for a two-step consecutive reaction in which every component had absorption were successfully resolved. The data matrix measured in the electrodegradation process of salicylic acid, in which the final product has no absorption, can also be resolved,with a satisfying result.
