ANALYSES OF ADSORPTION-KINETICS USING A STIRRED-FLOW CHAMBER .1. THEORY AND CRITICAL TESTS

A numerical solution for various instantaneous equilibrium and kinetic models is presented. It was found that rate data that could be described using an instantaneous equilibrium model could also be interpreted using a kinetic model. An analytical approach was developed to outline experimental methods that could be used to distinguish between instantaneous equilibrium and time-dependant reactions and to differentiate between solution-concentration-dependent kinetic models vs. those that are independent of solution concentration. By using this approach it is easy to decide whether rates of reactions can be measured using the stirred-flow method for specific experimental conditions. -from Authors
