✦ Synopsis
In flow-injection methods based on chemical reactions, simple one-step reactions are desirable, but more complex kinetics cannot always be avoided. The consecutive reaction considered here is A+ reagent(s) +B-+C. The response signal depends on the dispersion of the sample zone in the system and on the kinetics of the chemical reaction. The dispersion in a single-bead-string reactor is described by the tanks-in-series model. The reaction of paracetamol with hexacyanoferrate (III) and phenol is used for experimental verification. Rules for optimum reactor design are given, the reactor length being used as the optimization parameter. Comparison of the experimental and calculated peak heights at different reactor lengths confirms the optimization rules.
