%X Competition kinetics was used to determine the binding constants of the dye pyridine-2-azo-p-dimethylaniline ( pada ) with &#946;- cyclodextrin (&#946;-CD), &#947;- cyclodextrin (&#947;-CD), 2,6-O-dimethyl-&#946;-cyclodextrin ( dm&#946; ), 2,3,6-O-trimethyl-&#946;-cyclodextrin ( tm&#946; ) and hydroxypropyl-&#946;-cyclodextrin ( hp&#946; ) at 25.0&#176;. Stopped-flow spectroscopy was used to monitor the change in kinetics after cyclodextrins had been added to the Niaq2+ and pada reactant solutions. The values of the binding constants/dm3 mol-1 with pada were 300 for &#946;-CD, 40 for &#947;-CD, 550 for dm&#946;, 210 for tm&#946; , and 350 for hp&#946;.
