Abstract

The mixing efficiency of a standard manifold and a ball mixer for flow-injection systems were studied and compared. The reactions of ozone with indigo trisulphonic acid and chlorate ion with iodide ion in acidic medium were used as test reactions for the investigation. Mixing efficiency was shown to approach unity for both the ball mixers and the standard flow-injection analysis manifold. Effects of reaction rates, dispersion of the injected sample and diffusion are studied. As expected the faster the rate of the reaction the more marked the effect of the mixing efficiency.
