Kinetic Composition Measurement
Kinetic methods involve the measurement of chemical reactions or processes in a time-dependent manner. Rates of dynamic processes are measured rather than the properties of a system at equilibrium. Of course, this approach is a central one for the study of chemical reactions and reaction mechanisms; however, it has much value in analytic chemistry; that is, in the determination of the composition of materials. This fact has been recognized for some time, but in recent years, there has been resurgence in interest in the use of kinetic methods in analytic chemistry. There have been several world congresses on this subject and numerous monographs [1,2], and the number of papers on kinetic methods has dramatically increased in the last decade .
