Comparison Of Mixing Devices For Flow Injection Determinations Based On Doublet Peak Formation, Julian Tyson, Rt Echols

Chemistry Department Faculty Publication Series

The well-stirred tank model accurately describes the separation (At) between flow-injection doublet peaks and has been found to be applicable to a variety of mixing devices that do not contain moving parts such as a magnetic follower. The reaction between lanthanum(III) and methyl thymol blue was used as a model reaction for a comparison study of mixing devices. Column and open-tubular reactors were included in the study. Mixing devices were compared on the basis of the straight line fit of At versus the natural logarithm of the concentration of injected La(III). The linearity of the At-ln[La(III)] plots was equivalent for …
